What is the difference between permanent magnets and electromagnets?

Back

Permanent magnets maintain a constant magnetic field, while electromagnets can be turned on and off by controlling the electric current.

Front

What is magnetic polarity?

Back

Magnetic polarity refers to the orientation of the magnetic field, with a north pole and a south pole.
