Consider a circular loop of radius R in the presence of a uniform magnetic field. Which of the following statements is true?
A) Doubling the magnetic field would result in the same change in flux as doubling the radius would.
B) Doubling the angle between the magnetic field and the surface will double the magnetic flux.
C) Changing the angle between the axis of the coil and the field from 90o to some θ angle would result in the same change in flux as doubling the area of the coil.
D) Halving the radius of the coil halves the magnetic flux through the coil.
E) None of the above are true.

A circular coil with 150 loops and a radius of 10 cm is initially oriented in a 0.5 mT magnetic field, with the axis of the coil and the field at a 30o angle. After some time, the coil rotates so that the field is at an angle of 40o to the plane of the coil, and the field strength drops to 0.3 mT. What is the change in magnetic flux during this time?
