Question

Aflat circular coil of 1 cm radius consists of 5 tightly packed turns and is rotated at 10 revolutions per second about an axls that is perpendicular to a uniform magnetic field of magnitude 3.5 T. If the coll has an internal resistance of 0.25 Ohms, what is the magnitude of the peak current induced in the coil? O 3.5 A 2.9 A O 14 A 6.3 A O 0.74 A 5 pts Question 12 The figure shows a stationary conducting loop adjacent to a horizontal current-carrying wire. For which of the following conditions will a counter-clockwise induced current circulate in the stationary loop?
