the magnetic filed in the coil of 100 turns and 40 square cm area is increased frm 1 tesla to 6 tesla in 2 second. the magnetic field is perpendicular to the coil. the emf generated in it is

10 rase to 4 v

1.2 v

1.0v

10 rase to -2 v

please give me the full answer experts

Given:

No of turns, N = 100

A = 40 cm² or 4 × 10^-3 m²

dB = 5 T

dt = 2 sec

Now as we know

Magnetic flux linked with the coil at any instant:

Φ_B = NBA cosθ and if the magnetic field is perpendicular to the coil, θ = 0°

And induced emf, e = dB/dt

Substitute the values and get the desired answer
