When a magnet moves in a coil of wire, it induces an electric current in the wire through electromagnetic induction. This phenomenon is described by Faraday's law of electromagnetic induction. The induced current flows in the wire in response to the changing magnetic field produced by the moving magnet.
The two main types of galvanometers are moving coil galvanometers and moving magnet galvanometers. Moving coil galvanometers use a coil of wire that moves in a magnetic field, while moving magnet galvanometers use a magnet that moves in a coil of wire.
This is called electromagnetic induction. As the magnet moves, it creates a changing magnetic field which induces a current to flow in the wire coil according to Faraday's law of electromagnetic induction.
electric current in the coil of wire.
When a magnet moves through a coil of wire, it induces a change in magnetic field within the coil, which in turn generates an electric current. This phenomenon is known as electromagnetic induction, discovered by Michael Faraday in the 19th century. The amount of current produced is directly proportional to the rate at which the magnetic field changes.
When you move the magnet back and forth near a coil of wire, it induces an alternating current in the wire. The direction of this induced current changes as the magnet moves due to Faraday's law of electromagnetic induction, which states that changing magnetic fields induce an electromotive force (emf) in a conductor.

The most common way is with a magnet and a coil of wire. Have either the magnet or the coil (it doesn't matter which) fixed in place and the other one attached to a membrane that will vibrate with the sound. When a magnet moves past a coil of wire, it causes an electric current in the wire.
the moving magnet creates a changing magnetic field around the coil of wire. This changing magnetic field induces an electric current in the wire according to Faraday's law of electromagnetic induction.

You obviously cannot more a magnet through a coil in the direction of the current, because the magnet must move, axially, along the length of the coil, while the current moves radially, around the coil. However, if you move a conductor within a coil carrying a d.c. current, then the magnet will induce a voltage into that coil which will oppose the voltage applied to the coil.
When a magnet is moved through a coil of wire, it induces an electric current in the wire due to electromagnetic induction. This occurs because the changing magnetic field created by the moving magnet interacts with the electrons in the wire, causing them to move and generate an electric current. This phenomenon is the basis for generating electricity in devices such as generators and motors.
A magnet induces an electric current in a wire coil when there is a relative motion between the magnet and the coil, which generates a changing magnetic field. This changing magnetic field induces an electromotive force, leading to the flow of an electric current in the wire coil.
When a magnet moves near a conductor, such as a coil of wire, it creates a changing magnetic field. This changing magnetic field induces an electric current to flow in the wire, generating electricity through electromagnetic induction.
By moving a magnet through a wire coil, an electric current is induced in the wire due to electromagnetic induction. This current is generated as a result of the changing magnetic field produced by the moving magnet cutting across the wire coil. This process converts mechanical energy (movement of the magnet) into electrical energy (current in the wire).
