3. A square coil of wire (36.0 cm long on each side with 50 loops) moves at a constant
L = 0.3m B=0.84+ == 2.5s
speed of 0.40 m/s throughout the problem. The loop of wire moves from a region of
zero magnetic field to a region of magnetic field of strength 0.84 T directed into the
page as shown below. The square loop has a resistance of 7.50 2. The loop is
completely out of the magnetic field 2.50 s after first beginning to enter the region.

completely into the region of magnetic field?
b) What is the magnetic flux through the coil when it has fully entered the region with
magnetic field?
Find the magnitude of the current in the square coil i) as the coil enters the magnetic
field region, ii) as it moves through the region and iii) as the coil exits the region.
d) Find the direction of the current in the loop during these three time intervals (in
