Detailed explanation-1: -How could Theresa cause an electric current to flow through one of the copper wires? Move the magnet up and down near one of the coils.

Detailed explanation-2: -When a copper conductor is moved across a magnetic field, an emf or voltage is induced in the wire. Principle of Generation of EMF: Faraday’s Law of Electromagnetic Induction states that whenever there is a relative motion between a conductor and magnetic field, an emf will be induced.

Detailed explanation-3: -Given a bar magnet, how can you induce an electric current in a wire loop? An electric current is induced if a bar magnet is placed near the wire loop. An electric current is induced if a wire loop is wound around the bar magnet.

Detailed explanation-4: -A coil of wire becomes an electromagnet when current passes through it. The electromagnet interacts with a permanent magnet, causing the coil to spin. Voilà! You’ve created an electric motor.

Detailed explanation-5: -Magnetic fields can be used to make electricity Metals such as copper and aluminum have electrons that are loosely held. Moving a magnet around a coil of wire, or moving a coil of wire around a magnet, pushes the electrons in the wire and creates an electrical current.
