I am working on some physics homework and am stuck on this one. Any help would be great, thanks!
Two coils are connected to different power supplies. Each coil carries a current of 0.15 A. Coil A has 300 turns of wire. Coil B has 400 turns of wire. Which of these statements is correct? Select one: a. Coil B produces a larger magnetic field because it has more resistance. b. Coil B produces a larger magnetic field because it has more turns. c. Coil A produces a larger magnetic field because it has less resistance. d. Coil A produces a larger magnetic field because it has fewer turns of wire.
The magnetic field at the earth's surface can vary in response to solar activity. During one intense solar storm, the vertical component of the magnetic field changed by 2.8 μT per minute, causing voltage spikes in large loops of the power grid that knocked out power in parts of Canada.

1. Inner coil, radius R2 with N2 turns measure voltage Outer coil, radius R1 with N1 turns, AI/At = 5 amps/second We make a simple metal detector out of two circular coils of wire. The inner coil (radius R2, number of turns N2) is much much smaller than the outer coil (radius R1, number of turns N1), so you can assume the magnetic field is constant over the inner coil. We drive the outer coil with a current that increases at 5 amps/second. If there is no metal around, how much voltage is induced on the inner coil and how do you know?
