This problem involves magnetic fields produced by loops and solenoids as well as Fraday's law.
The magnetic field produced by a current loop:
Induced emf/Friday's Law:
A small, 1.70-mm-diameter circular loop with R = 1.40x10-2 Ω is at the center of a large 100-mm-diameter circular loop. Both loops lie in the same plane. The current in the outer loop changes from + 1.0 A to -1.0 A in 9.00x10-2 s.
What is the induced current in the inner loop?
Express your answer with the appropriate units.
