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. By measuring the induced emf, a device user can estimate the patient's breathing rate. Mindy needs the apparatus to be able to detect a change in area as small as 5.50 cm? occuring over a time period of 1.50 s. If the minimum emf that can be reliably detected is 2.00 x 10-4 V, what is the magnitude of the minimum external magnetic field that would be needed from the solenoid? magnitude of minimum external magnetic field: T
A power line carries a current I = 100 sin(380t), where I is in amps and t is in seconds. A clever engineering student wants to steal power by inducing emf in a rectangular loop of copper wire as shown below. If the student wants to induce a maximum emf in the loop equal to 1.7 V, what should be the length L of the loop? Assume that the magnetic field produced by the power line is uniform inside of the rectangular loo and equal to the magnetic field at the center of the loop. 5 mi To equipment I 0.5 m

You wish to construct a solenoid with a diameter of 2.00 cm that will produce a magnetic field of 3.40 x 10-2T at its center when a current of 12.0 A is passing through the coils. You want the resistance of the coil wire to be 5.80 N. The resistivity of the wire used is 1.70 x 10-8 N •m (at 20.0°C), and you are using a wire that has a cross sectional area of 3.14 × 10-8 m2. (Note that this solenoid may not necessarily be so tightly wound that the adjacent loops of wire will touch each other. Nonetheless, you may assume that it behaves like an ideal solenoid.) Determine the following. (a) number of turns needed on the solenoid turns (b) length of the solenoid
