A flexible wire loop with an area of 160 cm (change to m²) is in a uniform magnetic field of:
B = 0.025 T in the -z direction (into the page). Note: 1 T = 1 Vs/m².
The loop is pulled from both ends and collapsed in to a straight line in a time of 0.18 s.
a) What is the average induced emf & in the coil?
b) What is the direction of the induced current (as the loop is first collapsed)?
