A single loop of nickel wire, lying flat in a plane, has an area of cm and a resistance of A uniform magnetic field points perpendicular to the plane of the loop. The field initially has a magnitude of T and the magnitude increases linearly to T in a time of s What is the induced current in mA in the loop of wire over this time?
How does Faraday's law relate the change in flux per unit time to the emf? What are the initial and final flux values through the loop? How is the induced emf related to the resistance and induced current? Be careful of unitsnote the final answer should be expressed in mA mA
