Question

the rod of unit length is moving through the magnetic field of 1T . If the velocity of rod is 1 m/sec .Then induced emf is
a)1 v
b)0.25 v
c)0.6 v
d)0.5v​

Answer 1

Answer:

Correct option is

D

V

B

−V

A

=4 V

Given,

Length L=1m

velocity, v=4 m/s

Angle, θ=30

o

Magnetic Field,

B

⇀

=2T

Potential Difference,

V=BLvsin30

o

=2×1×4×sin30

o

=4 V

Potential difference is 4V
