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.
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.
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.
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).
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.
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.
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.
Whenever a conductor passes through a magnetic field, a voltage (not current!) is induced.
Show it on a meter or oscilloscope.
A magnetic field can induce an electrical current in a wire.
A current has to flow in the circuit to induce a force on the circuit
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.
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.
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).
A magnetic field can induce an electrical current in a wire.
An electrical current.
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.
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.
yes*edit: don't confuse moving with changing. A change in magnetic field strength/direction will induce an electric current.
yes*edit: don't confuse moving with changing. A change in magnetic field strength/direction will induce an electric current.
A time-varying magnetic field can be used to induce a current in an inductor
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.
Faraday says you will induce a current in the wire.
A current has to flow in the circuit to induce a force on the circuit
Motion of a coil within a magnetic field will induce a current in the coil if it can complete a circuit.
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.
