Mathematics · Electromagnetic Induction
A rectangular wire loop of sides 8 cm and 3 cm with a small cut is moving out of a region of uniform magnetic field of magnitude 0.3 T directed normal to the plane of the loop. The emf developed across the cut, if the velocity of the loop is 2 cm s-1 in a direction normal to the shorter side of the loop, will be:
- 11.8 × 10-4 V
- 21.2 × 10-4 V
- 31.3 × 10-4 V
- 44.8 × 10-4 V✓
Correct answer
4.8 × 10-4 V
