NEETPhysicsMagnetic Effects of Current

STATEMENT - 1 A rectangular current loop is in an arbitrary orientation in an external uniform magnetic field. No work is required to rotate the loop about an axis perpendicular to its plane. STATEMENT - 2 All positions represent the same level of energy.

Options

  1. AStatement - 1 is True, Statement - 2 is True; Statement - 2 is a correct explanation for Statement - 1.
  2. BStatement -1 is True, Statement -2 is True; Statement -2 is NOT a correct explanation for Statement -1.
  3. CStatement - 1 is True, Statement - 2 is False.
  4. DStatement - 1 is False, Statement - 2 is True.

Correct answer

A. Statement - 1 is True, Statement - 2 is True; Statement - 2 is a correct explanation for Statement - 1.

Step-by-step solution

( U =- B =- B ) Since, ( , B ) as well as ( ) remains constant, (U ) does not change.
