Homemade Magnet Wire Drawing Wire. You can reduce the diameter of a length of wire by pulling it through a draw plate -- a sheet of metal Wire Coating. To turn plain copper wire into magnet wire, you will need to give it a coating of insulating paint or Considerations. Making your own magnet. May 29, · Trim off the leads and expose more of the wire. Then measure the diameter of the wire, this wire is inch in diameter on top of the insulation, #24 AWG is to inch in diameter on top of the insulation that makes this magnetic wire #24 AWG according to the Insulated and Bare Copper Wire Table.
A magnetic coil is made using a conductor, generally an insulated copper wireand winding it around a core to produce an inductor, or a magnet. Basically, a wire that has electricity running through it produces a magnetic field. However, using a single wire would only generate a very faint field.
Consisting of more than one turn, or a loop of wire, a magnetic coil focuses the magnetic field, with every coil of wire supplying a small amount of magnetic field. Adding up all those magnetic fields together creates a stronger vector field that properly functions as a magnet. A simple magnetic coil is very easy to make, provided you have the necessary items for it.
Most of the items above can be easily found in your home, except for the magnet wire and the battery, which you can readily get from any hardware store.
For safety purposes, make sure that you have a proper location where you can build your magnetic coil, preferably in a workshop, garage, or basement. First, you need to have a magnet core. The iron nail, or any cylindrical piece of iron that you choose to use, will serve as the base from where the magnetic field will converge and eventually amplify.
There are other kinds of coils that make use of air as its core by either wrapping the copper wire around a thin cylindrical paper or winding the wire into a coil by itself, having no core at all in the middle. However, this is not advisable to do if you really want your magnetic coil to function strongly. Next, after selecting your core, wrap a strand of magnet wire around it. Remember that the more the coil is tightly spaced together, the better and stronger its magnetic force will be.
Then set aside approximately 6 to 7 inches of wire dangling at the end of the core. Proceed to wrap all the way to the other side of the core. Using glue or tape, adhere the coil to the core. Leave another 6 to 7 inches of allowance, and trim the rest of the wire off from its roll. This means that you now have two extra strands of wire at the opposite ends of the core that you will need.
Now, strip off the enamel coat from the two end wires by burning an inch of the enamel using a lighter or a match. Let it cool off for a few seconds before wiping it off with a clean cloth. Make sure that both end wires are now bare and devoid of the enamel. You now have your very own magnetic coil. To use your magnetic coil, connect the coil to an electric power source. Keep in mind though that the length of wire used to build the coil determines the resistance or impedance of the coil, and so will determine how much current will flow through it at a specific voltage.
Using the lantern battery as a source, attach the two end wires beneath the coils protruding out of the battery. It is then ready for use, and you can test it by trying to pick up items like nails, paper clips, coins, and other how to install ecosmart tankless water heater metal objects.

It only takes a few minutes to create a mini-electromagnet, but you will need some special materials to do it. After you have completed your first mini-electromagnet, you can also make modifications to your creation that might make the magnet more powerful.
To make a mini-electromagnet, you will need:  X Research source nail or screw at least three inches long and made from iron, zinc, or steel  X Research source some thin, coated copper wire scissors one AA battery electrical tape something to pick up, such as metal paperclips or tacks. Wrap the screw with thin coated copper wire. Take your nail or screw and begin wrapping the copper wire around it, but make sure that you leave a tail of about three inches. You will need this to connect the wire to the battery.
Then, leave another three-inch tail. Cut the wire about three inches past the end of the nail or screw. When you are done, you should have two three-inch pieces of copper wire hanging off of the ends of your screw or nail. Loop the ends of the wire. Take the wire pieces that are hanging off of the ends of your screw or nail. Then, curl up the ends of these pieces of wire a little bit, as if you are making a tiny loop on each end.
Attach the wire loops to your battery. Next, take the loops that you created and attach one loop to each pole of your battery. Attach one to the positive pole and the other to the negative pole. Use your magnet to pick things up. After you have attached the wires and secured them with tape, your mini-electromagnet is complete. Now you can use the wire-wrapped part of the nail or screw to pick up things like paperclips, tacks, nails, screws, and other small metal objects.
If they are loose or not connected, then the electromagnet will not work. Detach the copper wires from the battery when you are done using the magnet. The magnet will become hot if the wires are connected for too long. Part 2 of Try a different type of nail or screw. Try swapping an iron nail for a steel one to see if this increases or decreases the amount of paperclips you can pick up.
Use a larger screw or nail. Try upgrading your current screw or nail with a larger one to see if this makes the magnet more powerful. Attach a larger battery. Try swapping your AA battery for a D battery to see if this results in a more powerful magnet. Attach the wires to the D battery the same way that you would attach them to the AA battery. Add a switch. To add a knife switch, you will need two D batteries, more wire, and a knife switch, which you can find in most hobby stores.
Coil the wire around your nail or screw, then connect the wire from one end of the screw to your knife switch. Then, connect the wire from the other end of the nail or screw to the negative pole of one of the D batteries.
Next, connect a piece of copper wire between the positive pole of your battery that is connected to the screw and the negative pole of the battery that is not yet connected to anything. Finish the circuit by connecting a wire between the remaining positive pole and the knife switch. Close the knife switch and you should be able to pick up some paperclips or tacks.
Shawn Berlinghoff. The nail becomes hot because the wire is becoming hot. The wire becomes hot whenever it is too small for the amount of electricity you're trying to push through it. To stop this problem simply increase the gauge of wire.
Yes No. Not Helpful 1 Helpful A battery that does not have a charge will probably not work, or at least not as well as one that has a full charge. Try to do the experiment with a new battery for best results. Not Helpful 4 Helpful Harigovind R. Electromagnets acquire magnetism when electrons flow through them. That's why electromagnets work only when there is a potential difference at its ends. For making that potential difference, we connect a battery to it.
Yes, for sure. You can explain the magnetic effect of electric current using this experiment. Not Helpful 2 Helpful 9. Making a basic electro-magnet takes less than 10 minutes. However, you can modify your magnet after you finish the first design and keep testing new designs for hours if you want to.
Not Helpful 7 Helpful How do the electrons flow in this? Negative to positive or positive to negative? Electrons are negatively charged. They flow from the negative terminal to the positive terminal.
Not Helpful 6 Helpful Can I modify this so that I can remove a battery that is stuck at the bottom of a tube? If a battery is stuck at the bottom of a tube, chances are that the the chemicals in the battery have leaked out. They form a crust that needs to be dislodged before the battery can be removed. A slim screwdriver may work, but it may take several attempts before it can loosen the battery.
Not Helpful 0 Helpful 5. You can do this experiment just for fun, or use it to see how well different metals conduct electricity. For example, by switching out a steel nail for a zinc one, you may notice that one has more magnetic power than the other one. Not Helpful 9 Helpful What is the difference between wrapping a wire tightly and wrapping it loosely and not too close together?
Experiment with the number of wire wraps around the nail. The closer the winding, the stronger the magnetic field. The lines of magnet force overlap when the wires are closer, and results in a wider magnetic field. Wrap different nails with different winding. See how close a paper clip has to be before the magnet grabs it. Testing each version gives you insight to how to construct what you need.
