To make an electric motor, you create a circular loop of wire with radius 0.0100 m. You also have a magnet that can produce a relatively uniform magnetic field of strength 0.30 T 2. a. At a certain point, the magnetic flux through the loop is 2.00 x 10- T.m2; what is the angle between the plane of the loop and the field? (Note: the angle is zero if the loop is oriented like figure P27.21 in Practice, p. 495.)...

Two circular loops of wires with radius R_1 and R_2 lay in the same plane. For the case where R_1 is much greater than R_2 you can treat the magnetic field through loop 2 as being generated by the magnetic field at the center of loop 1 given by: B = mu_0 1/2 pir R_1 A) Calculate the algebraic expression for the mutual inductance between the two loops. B) If the current through loop 1 is increasing at 2 Amps/second,...
