Q1:

A conductor in x-y plane and having length 1 m is moving with a velocity V = (2i + 3j + k) m/sec. A magnetic induction field B = (i + 2j) Wb/m2 is applied to the conductor. The potential difference between the ends of the conductor is

A 0

B 4.88 V

C
6 V

D None of these

ANS:C -

6 V

= - (V x B) = - (2i + 3j + k) x (i + 2j) ∴ || = (E2x + E2y + E2z) = 6 v/m ∴ Potential Difference across 1 m length = 6.
