Explanation:
It is given that,
Area of nickel wire,
Resistance of the wire, R = 2.4 ohms
Initial value of magnetic field,
Final magnetic field,
Time, t = 1.12 s
Let I is the induced current in the loop of wire over this time. Te emf induced in the wire is given by Faraday's law as :
Induced current in the loop of wire is given by :
So, the induced current in the loop of wire over this time is . Hence, this is the required solution.
