The circuit given is a square 20 cm on a side. The magnetic field increases steadily from 0 T to 0.50 T in 10 ms. What is the current in the resistor during this time?
the magnetic field starts with a strength (B) of 50 mT into the paper and it decreases to zero and ends up changing direction to be 10 mT out of the paper in 2 ms. If a coil of square loops of wire parallel to the plane of the paper that is 10 cm on a side experiences that B change, how many loops must there be to get a total emf of 10 V?
(Next two questions) For a loop of current 2.5 A with radius 4 mm, calculate the magnetic field at the indicated locations.
