Figure 1 below shows a metallic rod MN of length l= 80cm, kept in a uniform magnetic field of flux density B= 0.5T, on two parallel metallic rails P and Q. Calculate the emf that will be induced between its two ends, when it is moved towards right with a constant velocity v of 36km/hr

Text Solution

Verified by Experts

l=80cm, B= 0.5T
v= 36km/hr= 10 m/s
Induced emf: e= Bvl `=0.5 xx 10 xx 80 xx 10^(-2)`
e= 4V
