A circular coil (950 turns, radius = 0.060 m) is rotating in a uniform magnetic field. At t = 0 s, the normal to the coil is perpendicular to the magnetic field. At t = 0.010 s, the normal makes an angle of ϕ = 45° with the field because the coil has made one-eighth of a revolution. An average emf of magnitude 0.065 V is induced in the coil. Find the magnitude of the magnetic field at the location of the coil.

If there is a diagram that can help me with understanding this problem better that would be awesome, thank you!
Given :
Number of turns in the coil,
Radius of the coil,
Time taken to rotate the coil,
Angle of rotation,
Avg. induced voltage in the coil,
Determine :
Magnetic field (B) at the location of the coil.
Magnetic flux through a coil of area A :
Induced voltage :
If the magnetic flux through the coil changes with time then an Emf will be induced in the coil.
