The energy change that takes place in an electromagnet is Electrical energy to magnetic energy. An electromagnet is a kind of magnet where the magnetic field is created by an electric current.
What is an electromagnet?
An electromagnet can be defined as a magnet that functions on electricity. Electromagnets are built out of a coil of wire (wire curled in series). This is more efficient in producing a magnetic field than just a wire running straight. This effect can be strengthened by winding a wire tightly around a powerful core, made of magnetic material, such as iron.
