A magnetic field is directed at a 40.0 angle to a plane circular loop of wire with a radius of 26.8 cm. a) draw a diagram showing the wire loop, angle and magnetic field. b) If the magnetic field strength is 0.398 T, what is the magnetic flux through the loop? c) If the magnetic flux decreases to zero in 2.50 ms, what is the induced emf in the wire loop?
