Question: What is the effect of increasing the number of turns in a coil on the induced EMF?

Options:

Correct Answer: It increases the induced EMF

Solution:

Increasing the number of turns (N) in a coil increases the induced EMF, as EMF = -N * (dΦ/dt).

What is the effect of increasing the number of turns in a coil on the induced EMF?

Correct Answer: Induced EMF increases.

Step 1: Understand what a coil is. A coil is a wire wound in a spiral shape.
Step 2: Learn about EMF. EMF stands for electromotive force, which is the voltage generated by a coil when it experiences a change in magnetic field.
Step 3: Know what 'turns' means. The number of turns refers to how many times the wire is wound around in the coil.
Step 4: Recognize the relationship between turns and EMF. The formula for induced EMF is EMF = -N * (dΦ/dt), where N is the number of turns and dΦ/dt is the rate of change of magnetic flux.
Step 5: Realize that increasing N means more turns in the coil. More turns means that the coil can capture more of the changing magnetic field.
Step 6: Conclude that if N increases, the induced EMF also increases. This is because the more turns you have, the greater the total voltage generated.
