Q: A loop of wire is moved into a magnetic field at a constant speed. What happens to the induced EMF as it enters the field?

Solution: As the loop enters the magnetic field, the rate of change of magnetic flux increases, leading to an increase in induced EMF.

Steps: 7

Step 1: Understand that a loop of wire is being moved into a magnetic field.
Step 2: Know that when the loop enters the magnetic field, it starts to experience a magnetic force.
Step 3: Remember that magnetic flux is the amount of magnetic field passing through the loop.
Step 4: As the loop moves into the magnetic field, more of the loop is inside the field, which increases the magnetic flux.
Step 5: The change in magnetic flux over time is what induces an electromotive force (EMF) in the loop.
Step 6: Since the loop is moving at a constant speed, the rate of change of magnetic flux increases as it enters the field.
Step 7: Therefore, as the loop enters the magnetic field, the induced EMF increases.
