مقناطیسی میدان میں بند لوپ میں چارج کو منتقل کرنے کا کام کیا ہے؟
- Zero
- Positive
- Negative

Explanation
The work done by a magnetic field in moving a charge along a closed loop is zero,
Because the magnetic force on the charge is always perpendicular to its velocity,
And therefore perpendicular to its displacement, resulting in zero work done.
