CAPE Physics Unit 2 · 2003 · Paper 1 · Question 2(c)(iii)

Two conducting rods are joined at right angles. A conducting bar in contact with the rods starts at the vertex and moves with constant velocity v = 4.20 m s^-1 perpendicular to the rods in a uniform magnetic field of magnitude 0.450 T directed perpendicularly out of the page.

Find the electromotive force (e.m.f.) induced in the moving rod at 2 seconds.
