The coil must experience a changing magnetic field in order to have a current induced. You can rotate the coil between the poles of a magnet, or rotate the magnet around the coil.

What happens if a coil is rotated between two magnets?

When a coil is rotated between two magnets, an electric current is induced in the coil due to the changing magnetic field. This phenomenon is known as electromagnetic induction. The induced current produces an electromagnetic force, creating a torque that causes the coil to rotate. This is the principle behind electric generators.


What happens when a coil is rotated between two magnets?

When a coil is rotated between two magnets, an electric current is induced in the coil due to the changing magnetic field. This phenomenon is known as electromagnetic induction and is the basic principle behind generators and electric motors. The amount of current induced depends on the speed of rotation and the strength of the magnetic field.


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

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.


What would not affect the strength of an induced current?

The strength of an induced current is not affected by the resistance of the circuit it flows through. The factors that affect the strength of an induced current are the rate of change of magnetic flux, the number of loops in the coil, and the material of the coil.


What happens when a coil of wires moves through a magnetic field?

When a coil of wires moves through a magnetic field, an electric current is induced in the wires through electromagnetic induction. This phenomenon is known as Faraday's law of electromagnetic induction. The direction and magnitude of the induced current depend on the speed and direction of the coil's motion through the magnetic field.

What are the reasons why a current is induced in a coil?

Current is not induced into a coil. It's voltage that is induced into a coil. If the coil is connected to a load, or even short circuited, then a current will flow as a result of the induced voltage -but it's the voltage, not the resulting current, that's induced!Voltage is induced into a coil because the the changing magnetic field, due to the change in current (0 to Imax or vice versa) applied to that coil. The process is called 'self induction'.


Is flow of induced current necessary when induces emf is being produced?

There is no such thing as an 'induced current'. Voltages are induced, not currents. If a voltage is self-induced into a coil, then that voltage will oppose any change in current. If a voltage is mutually-induced into a separate coil, no current will flow unless that coil is connected to a load.


What is emf induced in a motor's coil that tends to reduce the current in the coil of the motor?

BACK emf induced in a motor's coil that tends to reduce the current in the coil of the motor. The answer should be 'back'.

How is electromagnetic induction defined?

When there is relative motion between a magnet and a coil of wire, an electric current starts flowing in the coil. This phenomenon is called electromagnetic induction.When lines of a magnetic field cross the line of an conductor, electric current is induced in it.

What are the different ways to induce current in a coil?

Different ways to induce current in a coil are as given below:(1) If a magnetic field is changed round a coil then an induced current is set up in the coil. It can be done by taking a bar magnet and bringing it closer to the coil or taking it away from the coil.(2) If a coil is moved in a magnetic field, then again an induced current is set up in the coil.(3) If a coil is rotated in a uniform magnetic field, it may also cause an induced current in the coil.(4) If we take two coils and insert them over a non conducting cylindrical roll then on changing current flowing in one coil, an induced current is obtained in the other coil.CommentYou don't induce a 'current' into a coil; you induce a voltage. If that coil is open circuited, then no current will flow. If, on the other hand, the coil is connected to a load, or its opposite ends short-circuited, then the induced voltage will cause a current to flow. Remember, current will only flow if there is a load, or short circuit, and the value of the current will depend upon the value of the induced voltage and the resistance of the load or short circuit.


Why there is an induced current in a coil when a bar magnet is thrust out of the coil?

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.
