The plane of loop perpendicular to the magnetic field

The plane of loop with dimensions 10 cm × 11 cm is initially perpendicular to a uniform 0.1 T magnetic field. Find the change in flux through the loop if it is turned through 150 degrees about an axis perpendicular to the field lines.

?? Wb

Area A = 10 x 11 = 110 cm^2 = 0.011 m^2
Magnetic field B = 0.1 T
The initial flux:
Φ = B * A cos 0
= 0.1 * 0.011 * 1 = 1.1 x 10^-3 Wb
The final Flux :
Φ' = B * A * lcos 150l
= 0.1 * 0.011 * 0.87
= 9.5 x 10^-4 Wb

ΔΦ = Φ’ - Φ
=9.5 x 10^-4 - 1.1 x 10^-3
= 1.5 x 10^-4 Wb
