Asseration:Induced coil are made of copper.
Reason:Induced current is more in wire having less resistance.

A

If both assertion and reason are true and the reason is the correct explanation of the assertion.

B

If both assertion and reason are true but reason is not the correct explanation of the assertion.

C

If assertion is true but reason is false.

D

If the assertion and reason both are false.

Text Solution

Verified by Experts

The correct Answer is:
A
The inductance coils made of copper will have very small ohmic resistance. Due to change in magnetic flux a large induced current will be produced in such an inductance coil which will offer appreciable opposition to the flow of current.

Asseration: Induced potential across a coil and therefore induced current is always opposite to the direction of current due to external source. Reason: Lenz's law states that it always opposes the cause due to which it is being produced.

A: There may be an induced emf in a loop without induced current. R: Induced current depends on the resistance of the loop as well.

Assertion: Only a charge in magnetic flux will maintain an induced current in the coil. Reason: The presence of large magnetic flux through a coil maintains a current in the coil if the circuit is continuous.

Assertion : It is more difficult to push a magnet into a coil with more loops. Reason : Emf induced in the current loop resists the motion oif the magnet.

Explain different ways to induce current in a coil.
