Physics-Motional EMF
NEET Physics Motional EMF Assertion Reason Question
Type: Assertion Reason-assertion-Hard-Class 12
Assertion (A): A motional emf is generated when a conductor moves perpendicular to a magnetic field. | Reason (R): The Lorentz force causes a separation of charges in the conductor, 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
The NCERT context explains that the Lorentz force causes free electrons to move in the conductor, leading to charge separation and emf generation. This supports both statements as true, with R explaining A.
