Introduction: Creating an Electric Motor
How it will work: The electric motor will work by spinning a coil of wire over a magnet. When an electric current goes through a coil of wire it produces an electric field. By toggling this current on and off we will keep the coil from repelling the magnet and only have it on when it is attracted to the magnet This will keep the coil spinning, and as long as your battery has power your coil will keep spinning. That is how we hope your electric motor will turn out.
Step 1: Materials
1.Insulated copper wire (a reasonable amount, you wont need a whole spool) also have this wire not be too thin for it needs to be able to hold itself up 2. A magnet 3. A battery preferably a D battery, but you can use whichever battery, it is just a challenge to support the coil with out a D battery. 4. Electrical tape 5. Exacto Knife and if you do not use a D battery you will need to support the Wires that support the coil with something else. 6. 2 alligator wire clips if you are not using a D battery to power your electric motor
Step 2: Beginning the Asembly
Make a coil of wire with about 1.5 cm diameter and have the wire stick out on each end. This will be the coil that spins effectively creating an electric motor.
Step 3: Getting Your Coil Toggle on and Off As It Spins
Take on end of the coil and use the exacto knife to strip the wire completely. Then take the opposite end of the wire and strip half of the wire, so it will toggle on and off as it spins.
Step 4: Supporting Your Coil Above the Magnet
We had 2 dead D batteries to support our wires that will hold our coil above the magnet. We stripped both ends of the wire so we could form a complete circuit and looped it around so the coil will not wobble out when spinning at a decent RPM.Tto do this cut about a 8cm-10cm piece of wire and strip both ends. If you use a D battery to power your motor tape the wire to either end and that should suffice.
After this is completed you should have 2 wire supports either standing up straight or taped to either end of your D battery.
Step 5: Setting Up Your Battery and Magnet in Relation to the Coil Supports
Place the coil holders holders about 6cm away from each other if you are not using a D battery. If you are using a D battery the wires should be fixed on either end of the battery sticking straight up like the picture.
After this is done it is time to place the magnet. If you are using a D battery you should place the magnet between the wires like the picture, if you are not using a D battery, center the magnet between the support wires. You may have to raise the magnet with either the battery you are using or other modes of raising a magnet, it just isn't that complicated.
Step 6: Getting Your Coil Supports Ready for the Coil
If you are using a D battery you will not have this problem. but if you are not using a D battery then take one alligator clip and attach it to one port of the battery. Then take the other end of that alligator wire clip and attach it to one coil wire support. Then take the other alligator wire clip and repeat the process for the other port of the battery and the other wire coil support. after this step is complete it should look something like the picture from the previous step.
Step 7: Putting in Your Coil and Trying to Get It to Work
At this point your motor should be complete in every way but your coil. place your coil in the loops of your wire supports. At this point spin the coil a few times and try to get it to work. if you are lucky it will work the first time, but that was not the case for us when creating our motor.
Trouble shooting tips:
1. your coil: if your coil does not spin well on its own then you have a problem, try and make your coil in such a way that it can spin freely on the coil supports.
2. voltage: you may not have enough voltage to power your batter, try to hook some batteries up in parallel in addition to the battery you already have
3. bring your magnet closer to the bottom of the coil, if your coil isn't almost brushing your magnet then it is too far away, try and lower your coil supports or raise your magnet closer to the wire.
If these trouble shooting steps don't work make sure you have the circuit turning on and off with each spin of the coil. And if you can't get it going don't give up it took us a few tries to get it going and was a tough device to get working. Good luck with your electric motor!
