Understanding Faraday's Law

What does the minus sign in Faraday's Law equation represent?

• It denotes a positive change.

• It is a placeholder with no significance.

• It indicates a direct relationship.

• It represents Lenz's Law.

Which factor has an inverse relationship with induced voltage?

• Number of windings

• Area of the coil

• Magnetic field strength

• Time

If the area of the coil is increased, what happens to the induced voltage?

• It increases.

• It remains the same.

• It becomes zero.

• It decreases.

What is the relationship between magnetic field strength and induced voltage?

• Direct relationship

• Random relationship

• No relationship

• Inverse relationship

In the example of changing magnetic field strength, what was the final magnetic field strength?

• 75 milli Tesla

• 100 milli Tesla

• 50 milli Tesla

• 25 milli Tesla

What is the initial condition of the coil in the example of changing area?

• Fully inside the magnetic field

• Partially inside the magnetic field

• Coil is stretched

• No coil inside the magnetic field

How does decreasing the time affect the induced voltage?

• It has no effect.

• It increases the voltage.

• It decreases the voltage.

• It makes the voltage zero.

What happens to the induced voltage if the number of windings is increased?

• It becomes zero.

• It increases.

• It remains constant.

• It decreases.

In the example of changing time, what was the new time interval used?

• 2 seconds

• 3 seconds

• 4 seconds

In the example of changing the number of windings, what was the new number of windings used?

• 50

• 75

• 100

• 25
