Motors impact almost every single aspect of modern life. For example, motors are used in propellers, windmills, and other useful tools that contribute to the lifestyle we live today.
To give an introduction to a more simple type of motor, we will be learning how to create a battery powered motor only using a couple of materials. Using a D battery, magnet wire, a rubber band, paperclips, sandpaper, and a magnet... we will be able to accomplish the task of making your very own spinning motor! The way this motor works is through electromagnetic interactions: the interaction of current (or the flow of electrons), along with a magnetic field.
The point of this is to show how something so complex like an electric car's motor, can have similarities to something so simple as a motor built with accessible items.
Step 1: Gathering Materials
To be able to make this motor, you will be needing a couple of materials:
Once you have collected these items, you will be able to begin measuring up how much of the materials you will be needing.
Step 2: Measuring Magnet Wire
Measure a length of magnet wire that reaches from your hand to your shoulder. Then cut the wire after measuring the length.
Step 3: Sanding Magnet Wire
Take the wire and scrape off half the colored enamel off of the wire using sandpaper. Make sure only half of the enamel is scraped off.
Step 4: Shaping Magnet Wire
Once half of the enamel is scraped off, take the D battery and take the middle part of the wire and wrap the wire around the battery to obtain the perfect circular shape.
Then, take the ends of the wire and wrap the ends around the circular coil to have it keep the shape. (To prevent it from uncoiling into a slinky shape)
Step 5: Sanding Off ALL of One End
When the wire has a circular shape with two ends sticking straight out, take one of these ends and scrape off ALL of the enamel. Only one of the ends should have all of the enamel off, and one should still only have half of it scraped off.
Step 6: Shaping Paper Clips Pt. 1
Set aside the circular coil and take two paperclips. Take the paper clip and unfold it into a C shape.
Step 7: Shaping Paper Clips Pt. 2
Once the paperclip is in the C shape, take one of the bent ends and bend it upwards so that it will have a hook. Then repeat this with both of the paperclips.
Step 8: Attaching Paper Clips
Once you have the coil prepared and the paperclips shaped into the hook like shape, take the D battery and attach the paperclips to both the positive end and the negative end.
You attach these paperclips with the rubber band so they stay in place.
Step 9: Setting Up Motor
When the battery is set up with the paperclips standing up and acting as a hook, place the coiled wire on top so that the ends rest on the dip of the paperclip and it rests evenly. Then, you add the magnet directly under the hoop so it rests on top of the battery.
Step 10: Toubleshooting
Once you set up the motor and add the magnet under the coil, it should begin to run (and by run I mean spin)
If it doesn't seem to spin, check to see if it is twitching.
If it is twitching, its more than likely that the coil ends are not even enough that it wont dip downwards and prevent it from not spinning. So, make sure that the ends are sitting evenly and straight across the paper clip hooks.
Another common issue is making sure that ALL of the enamel on ONE of the ends are sanded off and that the other only has HALF sanded off. If you sand off too much enamel off of the magnet wire, then it may prevent the motor from running. So make sure that you only sanded off what was necessary.
Lastly, if the coil is too far from the magnet, it may prevent it from running fast enough, or running at all. Bring the coil closer to the magnet but not so close it touches.
Sometimes, all it needs is a little nudge!
Regardless of the adjustments it needs, enjoy your very own spinning battery motor that was made only using basic products.
