Answer:
An electromagnet is a temporary magnet. An electromagnet has a magnetic field created by electric current. Electricity and magnetism are closely related to each other. Wherever there is electricity, there is a magnetic field, and wherever there is magnetism, there is potential for an electric field. The field disappears when the current is turned off. Electromagnets are essential to the creation of electrical devices such as motors, generators, speakers, computers, and MRI machines. They are popularly recognized for their role in picking up and moving heavy magnetic objects like scrap iron.
