B. 0.35 A
Explanation
The problem involves Faraday's Law of Electromagnetic Induction, which states that a changing magnetic field induces an electromotive force (EMF) in a circuit. The induced EMF (
) can be calculated using the formula
, where
is the magnetic flux. Given the rate of change of the magnetic field, we can determine the induced current using Ohm's Law
, where
is the resistance of the circuit.
