How do you increase the induced voltage?
Add more turns to the coil, move the magnet faster, increase the strength of the magnet.
1 of 5
What is electromagnetic induction?
It's when a voltage is produced when a magnet moves into a coil of wire.
2 of 5
How can you make a simple motor
A simple motor can be built using a coil of wire that is free to rotate between two opposite magnetic poles.
3 of 5
How can you make an electromagnetic stronger?
Adding more turns to the coil, increasing the current flowing through the coil, wrapping the coil around an iron core.

When an electric current flows through a wire what does it create around it?
When an electric current flows in a wire it creates a magnetic field around the wire.
