What happens to the current in the coil and the magnetic field around the coil?

A coil of wire (solenoid) When an electric current flows, the shape of the magnetic field is very similar to the field of a bar magnet. The field inside a solenoid is strong and uniform. The small magnetic field caused by the current in each coil add together to make a stronger overall magnetic field.

What is change in magnetic flux?

Any change in magnetic flux induces an electromotive force (EMF) opposing that change—a process known as induction. Motion is one of the major causes of induction.

When the magnetic flux linked with a bulk metal piece of conductors changes currents are induced in it?

Eddy Currents are the currents induced in the body of a conductor when the amount of magnetic flux linked with the conductor changes. These were discovered by Foucault in the year1895 and hence they are also called Foucault currents.

Why change in magnetic flux produces current?

To read magnetic data, the ferromagnetic material is moved past the coil of wire. The changing magnetic field caused by the material’s motion induces a current in the coil of wire proportional to the change in field.

How can the force of a magnetic field being generated by a coil be changed?

The change could be produced by changing the magnetic field strength, moving a magnet toward or away from the coil, moving the coil into or out of the magnetic field, rotating the coil relative to the magnet, etc. Faraday’s law is a fundamental relationship which comes from Maxwell’s equations.

How does changing flux induce EMF?

Whenever the flux passing through the coil changes by any way (like either changing angle, magnetic field or area of coil), we are actually producing a relative motion between electrons and magnetic field. As a result, the electrons experience a magnetic force and shift to produce EMF.

When magnetic flux change through a solid conductor it induces?

Eddy currents is produced in any metallic conductor when magnetic flux is changed around it.

When magnetic flux changes around a metallic conductor eddy current is produced?

When a metallic conductor is moved in a magnetic field, magnetic flux is varied. It disturbs the free electrons of the metal and set up an induced amf in it. As there are no free ends of the metal i.e., it will be closed in itself so there will be induced current.
