Question

A 10 m long copper wire while remaining in the east-west horizontal direction is falling down with a speed of 5.0 ~m / s . If the horizontal component of the earth's magnetic field =0.3 10⁻⁴ ~Wb / m ^2 the emf developed between the ends of the wires is

Quantrex Academy · Accepted Answer

Correct answer: D. 1.5 mV

Given, l=10 ~m , v=5 ~m / s and H=0.3 10⁻⁴ ~Wb / m ^2 Induced emf e=H v l aligned & =0.3 10⁻⁴ 5 10 & =1.5 10⁻³ ~V & =1.5 mV aligned
