For the past few weeks my class has been doing some science activity. This week I have been with fi. We made a homo polar motor.
My goal was to make it spin.
We needed an AA battery, copper wire, and neodymium magnets we needed up to (3-4) of them.
- To make it spin we had to connect the magnets to the battery then we had to cut the copper wire about 10-15 center meters long after that we could bend the wire and make it our own shape I couldn’t do it so I just joined another group.
- when we have finished that we got given a sheet of paper.
- We had to write our goal.
- what we need and we also had five boxes to write the steps of how to make it.
- Here is mine.
- Goal make it spin what I need one AA battery 10-15 center meters of copper wire and 3-4 of neodymium magnets.
- Now my steps were gather materials, and cut the wire 10-15 center meters long.
- second step shape the wire into your own shape make sure there is a hook up the top so it go on the top of the battery.
- third step. We con bind the magnets to the bottom of the battery.
- And place the wire on top of the battery.
- Make sure the hook is touching the top of the battery.
- Step four if you have connected it properly your wire should spin.
- If the wire is not spinning you could change the shape of the wire or make sure the hook is touching the top and the bottom of the wire is around the magnets.
- When the electrons travel through the wire near the magnets field, they experience a special push or shove called the Lorentz force.
- this force acts like a tiny sideways nudge, trying to push electrons in a specific direction.
- In a homo polar motor, the wire is usually shaped like a loop. Because the Lorenz force acts on the electrons throughout the loop, it creates a force that tries to rotate the entire loop around the center of the magnet.
- This is like lots of tiny pushes all working together to spin the wire. I recommend that you try and make one of these it was really fun.
- If I got to change something about this experience it would be to change the thickness of the wire change the battery’s and put a different amount of magnets under neath the battery.
