Net Force on Closed Loop in Uniform FieldHardQuestion 20243
Question
Net force on a closed current loop placed in a uniform magnetic field is:
- ANIAB
- BZeroCorrect
- CNIAB sinθ
- DDepends on orientation
Correct answer
Zero
Explanation
In a uniform field, the forces on each element of the loop are equal and opposite for opposite sides → net force = 0. Only torque acts on the loop in a uniform field, not net translational force.
