Figure shows a straight wire placed between the pole pieces of a magnet. Induced emf will be developed across the ends of the wire when it is moved towards.

Options

  1. AN
  2. BS
  3. CP
  4. DQ

Correct answer

C. P

Step-by-step solution

The magnetic force on positive charge F = qv * B Therefore, as shown in figure +ve charge will be accumulated at end A and - ve charge will be accumulated at end C. Hence, an emf will be developed when rod will move along P.
