Question

a conductor of length 1meter moves at right angles to a uniform magnetic field flux density 1.5 Wb/m2 with a velocity of 50 m/sec.The induced emf will be

Answer 1

According to question

Magnetic Flux   = 1.5 Wb.m^2
velocity = 50 m/sec

Thus   induced emf = rate of change of magnetic flux 
                                = magnetic flux * Area
                                = 1.5 * 50 /1
                                = 75 Wb
