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

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

∙ 13y agoThe 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).

∙ 11y agoFirst 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.

The first is the principle of the dynamo and the third the principle of the transformer.

This induces an electric current.
It is the movement that is important, whether moving into, or out of, the coil.

What can induce an electrical current in a wire?
A magnetic field can induce an electrical current in a wire.
What conditions are necessary for magnetic field to produce a force on a wire?
A current has to flow in the circuit to induce a force on the circuit
How does changing current affect the magnetic force on a wire suspended in a magnetic field?
Current passing through a wire in a magnetic field creates its own magnetic force in some direction. If you increase the current, force will be increased. If the direction of current is changed, direction of force will also be reversed. Direction of current is found by applying right hand rule.
Does a coil carrying electric current create a magnetic field?
No, The magnet rotates/moves through the coil, inducing a current into the coil by disturbing the coils magnetic field. A transformer works the exact same way.
How does a magnet create electricity?
It is not the magnet alone, but the movement of a conductor (wire) in a magnetic field will induce a voltage (and a current, if it is connected in a circuit).
What can induce an electrical current in a wire?
A magnetic field can induce an electrical current in a wire.
What does a changing magnetic field induce?
An electrical current.
If a wire with no current passes a magnetic field of flux will voltage be induced into the wire?
Yes, for as long as the magnetic field is moving along the conductor. A static magnetic field will not induce current, a dynamic field is required.
Why does a transformer require alternating current?
In order to induce voltage as an output, a changing magnetic field is needed. To create a changing magnetic field in the transformer a changing current and that is an alternating current.
Does an electric current produces a magnetic field?
yes*edit: don't confuse moving with changing. A change in magnetic field strength/direction will induce an electric current.
Does a moving magnetic field produce an electric current?
yes*edit: don't confuse moving with changing. A change in magnetic field strength/direction will induce an electric current.
How is magnetism used to produce electricity?
A time-varying magnetic field can be used to induce a current in an inductor
How is mechanical force produced on a wire when it is passed through a wire in a magnetic field?
The movement through a magnetic field will induce a voltage; if there is a closed circuit, that will produce a current. The current, in turn, will have a magnetic field, which will interact with the external magnetic field. The direction of the interaction will be such that energy is conserved, i.e., it will tend to slow the wire down.
What is produced when a magnetic field moves relative to a closed wire loop?
Faraday says you will induce a current in the wire.
What conditions are necessary for magnetic field to produce a force on a wire?
A current has to flow in the circuit to induce a force on the circuit
Can magnets produce electric currents?
Motion of a coil within a magnetic field will induce a current in the coil if it can complete a circuit.
How does changing current affect the magnetic force on a wire suspended in a magnetic field?
Current passing through a wire in a magnetic field creates its own magnetic force in some direction. If you increase the current, force will be increased. If the direction of current is changed, direction of force will also be reversed. Direction of current is found by applying right hand rule.
