    In a magnetic field, what happens to the torque experienced by a current loop?

    Consider a loop with multiple turns, and how increasing the number of turns affects the torque.

    Torque decreases with more turns.Incorrect Answer
    Torque remains unchanged with more turns.Incorrect Answer
    Torque increases with more turns.Correct Answer
    Torque first increases, then decreases with more turns.Incorrect Answer

    Explanation:

    The torque (t) on a current loop is given by t = nIA × B, where n is the number of turns, I is the current, A is the area of the loop, and B is the magnetic field.

    Increasing the number of turns directly increases the torque proportionally.

    This means that the total torque is the sum of the torques on each individual turn, leading to a greater overall effect.
