Physics-Motional EMF
NEET Physics Motional EMF Assertion Reason Question
Type: Assertion Reason-assertion-Easy-Class 12
Assertion (A): A motional emf is generated in a conductor moving perpendicular to a magnetic field. | Reason (R): The separation of charges within the conductor due to the Lorentz force results in a potential difference across its ends.
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 states that the Lorentz force causes free electrons to move, creating a charge separation and emf in the rod moving perpendicular to the magnetic field.
