What is produced when a magnet spins within a coil of wires?

When a magnet spins within a coil of wires, what is produced? a magnetic field is created around the wire. When an electric current flows through a wire: Electricity will be produced.

What happens when a magnet moves towards a coil?

When a magnet is moved towards the coil then a current is induced in the coil due to the phenomenon of electromagnetic induction. Due to the relative movement between the magnet and the coil an electromotive force (EMF) is induced which in turn causes the current in the coil.

What material is produced when a coil of wire is wind around an iron nail?

A magnet made from just a coil of wire isn’t very strong. But when you coil the wire around an iron nail, the magnetic domains inside the nail line up and make a strong, temporary magnet.

How is magnetic flux produced?

If we use the field-line picture of a magnetic field then every field line passing through the given area contributes some magnetic flux. A field line passing through at a glancing angle will only contribute a small component of the field to the magnetic flux.

What material is produced when a coil?

Many electromagnetic coils have a magnetic core, a piece of ferromagnetic material like iron in the center to increase the magnetic field. The current through the coil magnetizes the iron, and the field of the magnetized material adds to the field produced by the wire.

Why emf is produced?

In nature, emf is generated when magnetic field fluctuations occur through a surface. In an electrical generator, a time-varying magnetic field inside the generator creates an electric field via electromagnetic induction, which creates a voltage difference between the generator terminals.

What is produced in this process of motion of the bar magnet in and out of the coil?

By moving this bar magnet “in” and “out” of the coil a current would be induced into the coil by the physical movement of the magnetic flux inside it. So what Michael Faraday discovered was a way of producing an electrical current in a circuit by using only the force of a magnetic field and not batteries.
