A square loop, with area 0.04 m, is in a uniform magnetic field. The magnetic field lines are perpendicular to the square loop. You squeeze the loop and reduce its area at a rate of 0.1 m²/s. a) If the induced emf is 22 mV what is the value of the magnetic field? B) If instead you kept the area of the loop constant, and did not squeeze it, at what rate would the magnetic field's magnitude have to change to induce the same 22 mV emf?
