A square loop of wire with side length 10 cm is moving
to the right with constant speed of 16 m/s. The loop has total
resistance of .8 ohms. It begins in a region with no magnetic
field, then enters a region of magnetic field (wider than 10 cm)
with a strength of .5 T pointing out of the page.
a) while entering the field what is the direction of the induced
current as seen from above the plane of the page?
b) while in the middle of the field what is the direction of the
induced current as seen from above the plane of the page?
c) while leaving the field what is the direction of the induced
current as seen from above the plane of the page?
d) before the loop enters the field, what is the magnitude of the
magnetic flux through the loop?
e) when totally in the field, what is the magnitude of the magnetic
flux through the loop?
f) as the loop enters the field, what is the magnitude of the
induced end around the loop?
g) as the loop leaves the field, what is the magnitude of the
induced current in the loop?
