Answer to Problem 7RAT

The correct option for the statement "A voltage will be induced in a wire loop when the magnetic field within that loop." is option (a).

Explanation of Solution

Electromagnetic induction is summarized by Law given by Faraday, according to which, the amount of induced voltage in a closed circuit or wire loop varies linearly with the variation in magnetic field associated with the loop.

Suppose a magnet is moved into a closed wire, there will be variation in the magnetic field and magnetic flux. So, a certain amount of voltage is induced in it. The change in the magnetic environment of the coil of wire or loop will lead to change in the induced voltage. So, when the magnetic field associated with the closed-circuit varies with the time, a voltage is induced in the circuit.

Conclusion:

Therefore, the correct option for the statement "A voltage will be induced in a wire loop when the magnetic field within that loop." is option (a).
