Question

Magnetic dipole moment is ______ of the loop, its direction is normal to the loop

• A. the sum of current and area
• B. the product of current and volume
• C. the sum of current and volume
• D. the product of current and area

Hint:

Magnetic dipole moment = current × area of loop.

Answer 1

The Correct Option is D

The magnetic dipole moment \( \vec{m} \) of a current loop is given by: \[ \vec{m} = I \cdot \vec{A} \] where \( I \) is the current and \( \vec{A} \) is the area vector of the loop (direction given by the right-hand rule).
