Physics-Bar Magnet
NEET Physics Bar Magnet Assertion Reason Question
Type: Assertion Reason-assertion-Hard-Class 12
Assertion (A): A bar magnet can be thought of as having a magnetic field similar to that of a solenoid. | Reason (R): At a large distance, the magnetic field of a bar magnet can be modeled using the equation of an electric dipole by appropriate replacements.
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 a bar magnet can be compared to an equivalent solenoid, and its magnetic field at large distances can be derived from the equation for an electric dipole by making appropriate substitutions.
