how is the number of loops related to the maximum induced emf in the coil (proportional, inverse, squared, et cetera)? and why?
Since the number of loops is directly proportional to the total area of the coil, how is the total area of the coil related to the maximum induced emf? and Why?

a. A 117‑turn circular coil of radius 2.63 cm and negligible resistance is immersed in a uniform magnetic field that is perpendicular to the plane of the coil. The coil is connected to a 16.7 Ω16.7 Ω resistor to create a closed circuit. During a time interval of 0.125 s,, the magnetic field strength decreases uniformly from 0.447 T to zero. Find the energy, in millijoules, that is dissipated in the resistor during this time interval. b. Mindy, a medical device...

20 Mindy, a medical device engineer, is designing an apparatus to monitor the breathing of a patient. The apparatus consists of a stretchable loop of conductive material wrapped in a small band around the patient's chest. A constant uniform external magnetic field is produced by a nearby solenoid. As the patient inhales, his chest expands, stretching the chest band. The resulting increase in the area of the loop causes an emf to be induced in the loop....
