Why there is an induce current in a coil when a coil is compressed in a magnetic field?

Answer 1

compressing a coil in a magnetic field means that there is a relative movement of the the said coil existing in a magnetic field, hence current will be induced. induction law.

Another Answer

'Current' is not induced into a coil. It's voltagethat's induced; if the coil forms a closed loop, then current will flow; if there is no closed loop, then no current will flow.

The induced voltage results from either a change in current through the coil, or from the relative movement between the coil and an external magnetic field.

Answer 2

photons are trapped in the magnetic field when the photon hits the electron of the copper coil the photon take the spot of the electron , its free to move

.

Answer2: The induced current is a consequence of the conservation of the magnetic field.

Answer

Current isn't induced into a coil -it's voltagethat is induced. Any current flows as a consequence of this induced voltage only if there is a load connected to the coil.

Answer 3

The electrons moving through the current are atomically magnetic, and create a magnetic field around all currents. To find this magnetic field you could use the left hand rule (where you point your thumb in the direction of the current and your fingers curling represents the magnetic field movement).

Answer 4

First of all, there is no such thing as an 'induced current'. What is being induced is a voltage. Michael Faraday discovered that whenever there is relative movement between a magnetic field (in this case, produced by a magnet) and a conductor (in this case, a coil), a voltage is induced into the conductor.

Answer 5

In 3 ways: By moving the coil in a magnetic field, by moving a magnetic field relative to the coil, or by supplying alternating current in a one coil and placing a second coil in the first's magnetic field. The first is the principle of the dynamo and the third the principle of the transformer.

Answer 6

The magnetic lines of force surrounding the bar magnet, cut through the coils of wire, causing electrons to move.

This induces an electric current.

It is the movement that is important, whether moving into, or out of, the coil.

Answer 7

When a coil is compressed in a magnetic field, the magnetic flux linked with the coil changes. According to Faraday's law of electromagnetic induction, a changing magnetic flux induces an electromotive force (emf) and therefore an induced current in the coil. This phenomenon is the basis for many electrical devices and systems such as generators and Transformers.

Answer 8

Whenever a conductor passes through a magnetic field, a voltage (not current!) is induced.

Answer 9

Show it on a meter or oscilloscope.
