A horizontal straight wire 10 m long extending from east to west is falling with a speed of 5.0 ms, at right angles to the horizontal component of the earth's magnetic field, `0.30 xx 10^(-4)Wb m^(2)`
What is the instantaneous value of the emf induced in the wire?

Text Solution

Verified by Experts

(b) (i) `epsilon = B_(H)`lv
Here `B_(H) = B cos theta`
(ii) The direction of induced emf is from west to east.
(iii) East end of the wire is at higher potential.
