Question

(1) A rectangular loop of wire that is 12 cm wide and 24 cm long is placed in a region where the magnetic field is B = 1.1 T and directed perpendicular to the plane of the loop. What is the magnitude of the magnetic flux through the loop?

(2) The loop in the figure below is rotated out of the plane of the drawing while B is kept constant. You can assume the rotation axis is along the horizontal direction in the figure.

(a) Does the magnitude of the flux through the loop increase or decrease with time? (Assume the loop has not had time to rotate by more than 90

Explanation / Answer

1) magnetic flux = B*A = 1.1*0.12*0.24 = 3.168*10^-2 weber

2)

a) decreases

b) clockwise
