A rectangular loop of wire weighing 341 mg with a 143 m2 falls vertically under gravity. The loop is oriented vertically, and it has. a horizontal width of 18 cm and height of 20 cm. It falls into a 251 mT magnetic field whose interface is horizontal. When the wire enters the field, the wire loop slows down to its terminal speed in a matter of microseconds. (a) What is the loop's speed while it enters the field? m/s (b) What is the force felt by the wire loop? mN (c) How long does it take the loop to become fully immersed in the field? ms B
