(a) changes.
(b) aligns with the electric field.
(c) is at right angle to the electric field.
(d) converts to magnetic energy.
Expert Solution & Answer
To determine
The correct option for the statement "A voltage will be induced in a wire loop when the magnetic field within that loop."
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).

- For each of the actions depicted below, a magnet and/or metal loop moves with velocity v→ (v→ is constant and has the same magnitude in all parts). Determine whether a current is induced in the metal loop. If so, indicate the direction of the current in the loop, either clockwise or counterclockwise when seen from the right of the loop. The axis of the magnet is lined up with the center of the loop. For the action depicted in (Figure 5), indicate the direction of the induced current in the loop (clockwise, counterclockwise or zero, when seen from the right of the loop). I know that the current is clockwise, I just dont understand why.
