Help with homework plz?
A circular loop of radius 0.0400 m is
oriented 75.0 degrees to a magnetic
field. If the magnetic flux through the
loop is 9.59 x 10^-7 Wb, what is the
strength of the field?
I need help with this plz I don't understand this well plz help I will give best answer...

Φ = B S cosθ
B = Φ / (S cosθ) = Φ / (π r2 cosθ)
θ = 75 - π/2 = 25 (angle between B and the normal to the loop surface)
B = 9,59x10^-7 / (3.14*1.6x10^-3*cos25) = 2.11x10^-4 T
