Question

Among the following statements:

A) A magnet of moment $M$ is bent into a semicircle, then its magnetic moment decreases

B) Magnetic moment is directed parallel to axial line from south pole to north pole

• A. A true & B false
• B. A false & B true
• C. A and B are true
• D. A and B are false

Answer 1

The correct option is C A and B are true

Magnetic moment is directed parallel to axial line from south pole to north pole
When the magnet is bent to form a semicircle, the effective distance between the poles decreases.
