STANDARD Physics Magnetic Force on Current Loop MCQ Question
Type: MCQ-conceptual-Medium-Class 12
A circular loop of radius R carrying a current I is placed in a uniform magnetic field B perpendicular to the loop. The force on the loop is
A
2πRIB
B
2πR²IB³
C
R²IB
D
Zero
Correct Answer
Option D
Detailed Explanation
The net force on a current-carrying loop in a uniform magnetic field is zero because the forces on opposite sides of the loop cancel each other out.
