To find out how electromagnetism works by constructing an electromagnet and be able to answer the question “How does electromagnetism work?”
Additional information
Do you ever wonder how the telephone, electric bell, and electric motors that run most of our appliances AT HOME WORK? Electricity can be transformed into energy of motion or mechanical energy and it is all because of the discovery made by Professor Hans Christian Oersted in 1820. Professor Oersted is a physics professor who discovered that a wire carrying electric current generated a magnetic field. He referred to this phenomenon as electromagnetism. An electromagnet operates only when there is a flow of electricity in the coil of the wire. Its magnetism can be turned on and off at will. It is made up of an iron core, wire, and source of electrical energy.
