The principles behind electric current and magnetic fields can be a bit technical, but building a basic engine is easy.We hunted for the facts on how to build an electric motor most effectively, and we have all the answers you need.
Step 1: Place four pencils on a piece of tape.
There is a two by two cluster.You will get something solid to wrap your coil around.It is possible to substitute the pencils for a cylinder that is half an inch in diameter.
Step 2: Wrap wire around the pencils.
Wrap your wire tightly around the pencils once you have them taped.Wrap the coil fifteen times in the middle of the wire.Remove the pencils from the middle once you have wrapped the coil.There are two loose leads at either end of the coil.
Step 3: Take the loose ends and loop them around the coil.
Wrap the loose ends around the coil multiple times.The coil wound will be kept tightly.Straight out from the coil, point the remaining loose ends.
Step 4: The battery needs to be secured.
If you want to hold the battery in place on a flat surface, use tape or clay.You won't have to hold it with your hands to connect it.The battery should be laying on its side so that you can easily reach it.
Step 5: Remove the ends of the coil wire.
The bare wire will be connected to the circuit only half the time if you use wire strippers to remove insulation on either end of the wire.The leads connect the battery to the coil.The motor will not work if you sand the wire all the way around.
Step 6: A needle is used to move each end through the eye.
The perfect holder is a needle.The end should be inserted into the eye of a separate needle.You can bend the paper clips to make a holder.
Step 7: The batteries should be taped to the needles.
It is time to hook your wire up to the battery after you have the wire in both needles.Attach one needle to the positive side of the battery.Attach the other needle to the negative side of the battery.The needles should point toward the battery and the eye at the top of the coil.The battery should not be touched by either needle.An electric current will run through the needles and wire when the leads are connected.It is a good idea to use rubber or insulated gloves.
Step 8: There is a coil with a magnet close to it.
A current can interact with a magnet when it flows through the coil.Either tape the battery underneath the coil or hold the magnet close to it.The closer the magnet is to the coil, the stronger it will be.
Step 9: The coil needs to be spun.
You can see what happens when you spin the coil.The coil may spin or not, depending on the direction the current is flowing and the side of the magnet that is interacting with it.Try spinning the other direction if the coil doesn't keep spinning.
Step 10: Try different methods.
You will get different results from different variations.If you change something, the coil may spin slower or not at all.Pick a stronger or weaker magnet if you want to move the magnet closer to the coil.These variations are fun to understand the forces of an electric motor.
