Arectangular loop (area = 0.15 m2) turns in a uniform magnetic field with b = 0.20 t. at an instant when the angle between the magnetic field and the normal to the plane of the loop is p/2 rads and increasing at the rate of 0.60 rad/s, what is the magnitude of the emf induced in the loop?

Explanation:

given,

Area of rectangular loop = 0.15 m²

Magnetic field = B = 0.20 T

angle between magnetic field and the normal to the plane = π/2

increasing at the rate = 0.60 rad/s

magnitude of emf induced = ?

induce emf through the loop

      Φ = BA cos θ

now substituting all the given values

the magnitude of induced emf  is equal to

nah.   i'm just sleepy.
