When you move the loop slowly, the change in magnetic field around the loop is gradual, resulting in a lower induced current. On the other hand, when you move the loop quickly, the change in magnetic field is more rapid, leading to a higher induced current. Therefore, the speed at which the loop is moved directly affects the magnitude of the current induced in the loop.
In general, the faster the loop is moved, the higher the induced current will be. This is in accordance with Faraday's law of electromagnetic induction, which states that the induced electromotive force (EMF) in a circuit is directly proportional to the rate of change of magnetic flux through the circuit. Therefore, the speed of the motion of the loop plays a critical role in determining the magnitude of the induced current.
Explore: Try moving the loop slowly, then fast. Observe the magnitude of the current as you do this. How does the speed of the loop affect the current?
