Answer 1

Learning objective: An electromagnet is a type of magnet in which the magnetic field is produced by an electric current, typically by winding a wire into a coil around a ferromagnetic core. The magnetism exists only when the current flows.Key words: Electromagnet, Electric Current, Magnetic Field, Coil, Ferromagnetic Core, Temporary Magnet.

Answer 2

## Step 1:To answer the question about electromagnets, we need to define what an electromagnet is.## Step 2:An electromagnet is a type of magnet where the magnetic field is produced by an electric current. The magnetic field disappears when the current is turned off.## Step 3:Key words that are important for understanding and explaining electromagnets include: electric current, magnetic field, coil, ferromagnetic core, and temporary magnet.
