NEET Physics Motional EMF Assertion Reason Question

Type: Assertion Reason-assertion-Easy-Class 12

Assertion (A): The induced motional emf in a conductor moving perpendicularly to a magnetic field can be calculated using the expression Blv.

Reason (R): The Lorentz force on charge carriers in the conductor is responsible for the separation of charges, leading to an emf.

A

Both A and R are true, and R is the correct explanation of A.

B

Both A and R are true, but R is not the correct explanation of A.

C

A is true but R is false.

D

A is false.

Correct Answer

Option A

Detailed Explanation

Both the assertion and the reason are true. The expression Blv is used to calculate motional emf, and this is explained by the Lorentz force causing charge separation, as described in Chunk 4.
