Question:
When a magnetic field is first turned on, the flux through a 40 -turn loop varies with time according to Φm=4.0t2−4.0t, where Φm is in milliwebers, t is in seconds, and the loop is in the plane of the page with the unit normal pointing outward.
What is the emf (in mV ) induced in the loop as a function of time?
