An 22-turn coil has square loops measuring 0.181 m along a side and a resistance of 4.55 12. It is placed in a magnetic field that makes an angle of 33.10 with the plane of each loop. The magnitude of this field varies with time according to B = 3.978, where t is measured in seconds and B in teslas. What is the induced current in the coil at t = 1.47 s?

As the wearer breathes, the radius of the loop of wire increases and decreases. When a person in the Earth's magnetic field (assume 59.5 pT) inhales, what is the average current in the loop, assuming that it has a resistance of 33.5 Q and increases in radius from 24.3 cm to 26.5 cm over 0.91 s? (Assume that the magnetic field is perpendicular to the plane of the loop.) Submit Answer Tries 0/99 Post Discussion Send Feedback
