Two straight conducting rails form a right angle where their ends are joined. A conducting bar in contact with the rails start at the vertex at t = 0 and moves with a constant velocity v along them as shown. A magnetic field B is directed into the page. The induced emf in the circuit at any time t is proportional to :
- t0
- t
- v
- v2
Answer
(B) t, (D) v 2
