B P1. [10 points] A circular loop of wire with radius 2 cm is in a magnetic field with magnitude B = (4.0 - 2t + 0.2t2) T. The field is parallel to the page, the plane of the loop is perpendicular to the page, and the angle shown is between the loop's axis and the field. a) [4 points] What is the magnitude of the induced EMF at time t = 2 s? b) [3 points] What is the direction of the induced EMF at that time (if the loop is viewed from above)? [3 points] Does the EMF ever change direction? If so, at what time
