What does an electromagnet do and how does it differ from a regular magnet?
An electromagnet is a type of magnet that uses electricity to create a magnetic field. It can be turned on and off by controlling the flow of electricity. In contrast, a regular magnet is always magnetic and does not require electricity to function.
How is an electromagnet differ from a regular bar or horseshoe magnet?
It requires a current through a coil of wires.
How is an electromagnet different a bar magnet?
a electromagnet is bigger than a bar magnet
Which is better a permanent magnet or an electromagnet?
electromagnet
How does an electromagnet's magnetic field differ from that of a permanent magnet, and does an electromagnet possess both a north and south pole?
An electromagnet's magnetic field can be turned on and off by controlling the electric current flowing through it, while a permanent magnet's field is always present. An electromagnet can have both a north and south pole, depending on the direction of the electric current.
