A rectangular circuit sits in a uniform magnetic field. It has a height of h = 0.7 m and width of w = 1.3 m and a resistor with R = 2 O . The magnetic field points out of the page and starts at a magnitude of B = 3.5 T and decreases at a rate of 0.6 T/s.
a) What is the magnetic flux, FB, at the beginning when B = 3.5 T?
b) What is the voltage induced in the loop?
c) What current flows through the loop due to the induced voltage?
d) Does the current flow CLOCKWISE or COUNTERCLOCKWISE?
e) When the external magnetic field is at B = 2 T, what is the force on the left side (of length h = 0.7 m) due to the current flowing in the external magnetic field?
