A straight wire of length 0.20 m moves at a steady speed of {{}} 3.0 m s^-1 at right angles to the magnetic field of flux density 0.10 T. The e.m.f induced across ends of wire is

Question

Quizplus · Accepted Answer

The e.m.f (voltage) induced in a wire moving through a magnetic field is given by the formula $ \varepsilon = Bvl $, where $ \varepsilon $ is the induced e.m.f, $ B $ is the magnetic flux density, $ v $ is the velocity of the wire, and $ l $ is the length of the wire. Substituting the given values: $ \varepsilon = 0.10 \, \text{T} \times 3.0 \, \text{m/s} \times 0.20 \, \text{m} = 0.06 \, \text{V} $.
