Shrinking Loop. A circular loop of flexible iron wire hae an initial circumference of 155 cm: but its circumference is decreasing at a constant rate of 150 emails clue to a tangential pull on the wire. The loop is in a cenetant uniform magnetic eld of magnitude 1.00 T : 1.I.rhich is oriented perpendicularto the plane of the loop. Aeeume that you are facing the loop and that the magnetic: eld points into the loop. Part A Find the magnitude of the emf 5 induced in the loop after exactly.I time 5.0135 has passed since the circumference of the loop started to decrease. Find the direction of the induced current in the loop 35 1.riewed leaking along the direction of the magnetic eld
