Question

What is necessary to make a electromagnet

Answer 1

An electromagnet is a type of magnet in which the magnetic field is produced by an electric current. It behaves exactly like a permanent magnet, like those magnets commonly used to stick items to our fridge.

To make a permanent magnet we need:

- One iron nail ( Could be fifteen centimeters (6 in) long )

- Three meters (10 ft) of copper wire

- One or more D-cell batteries

To make the electromagnet, we need to:

1. Wrap the Wire Around the Nail

2. Connect the Battery

And you are all set!
