How can I build an electromagnetic motor for my grade 11 Physics class?

[doolvision]

Hello everyone. First time i found this side from a buddy of mine told me to check it out for help. For my grade11 Physics class we need to build an electromagnetic motor with 4 electro magnets ATLEAST and no higher then 9volt battery.

I've looked everywhere and cannot find a simple intructions to making one.

Its an easy principle that i don't understand and to make it harder they give a project on it.

Anyone can lead me in the right direction?

Thanks in advance and keep the help alive!

Surely you can find sources on the internet that tell you how a motor works. Most of them will show a loop of wire rotating in the field created by a permanent magnet. However, you could make a motor with a magnet rotating in the field created by electromagnets that are being turned on and off as the magnet spins. You would want the electromagnets to be turned on in pairs with each magnet in a pair on opposite sides of the rotating magnet. Two pairs (the minimum 4 magnets you must have) would work, but 3 or 4 pairs would be great.

How could you make a pair of electromagnets with one continuous wire that have a space between the two magnets with the poles aligned as in this little diagram?

What would you have to do the change the polarity of the two magnets?

Hello! It's great that you are interested in building an electromagnetic motor for your Physics class. This type of motor is based on the principle of electromagnetic induction, which is the creation of an electric current in a conductor by changing the magnetic field around it.

To build an electromagnetic motor, you will need a power source, such as a 9-volt battery, and four electro magnets. The electro magnets can be made by wrapping wire around a metal core and connecting it to a power source. When electricity flows through the wire, a magnetic field is created around the core.

To make the motor, you will need to arrange the four electro magnets in a circular shape, with the poles facing each other. Then, connect the magnets to the battery in a way that will create a continuous flow of electricity through the magnets. This will create a rotating magnetic field, which will interact with the magnets to produce motion.

It's important to note that the strength and placement of the magnets can affect the performance of the motor. Also, it's recommended to use a low voltage power source for safety reasons. You can find more detailed instructions and diagrams online to help you with your project.

I hope this information helps you in building your electromagnetic motor. Good luck with your project!
