Electromagnetism and Oscilloscope Experiment Quiz

What is the relationship between EMF and the rate of change of magnetic flux linkage according to Faraday's law?

• EMF is proportional to the square of the rate of change of magnetic flux linkage.

• EMF is unrelated to the rate of change of magnetic flux linkage.

• EMF is directly proportional to the rate of change of magnetic flux linkage.

• EMF is inversely proportional to the rate of change of magnetic flux linkage.

In the experiment, what is varied to test the relationship between maximum EMF and frequency?

• The number of coils in the circuit.

• The distance between the magnet and the coil.

• The strength of the magnet.

• The speed of rotation of the magnet.

How is the peak EMF measured using an oscilloscope?

• By measuring the amplitude and multiplying by volts per division.

• By measuring the horizontal distance and multiplying by time per division.

• By measuring the time period and multiplying by volts per division.

• By measuring the frequency directly.

What formula is used to calculate frequency from the time period?

• Frequency is the square of the time period.

• Frequency is the inverse of the time period.

• Frequency is the product of the time period.

• Frequency is the sum of the time period.

What indicates a correct relationship between maximum EMF and frequency on the graph?

• A curved line through the origin.

• A horizontal line.

• A straight line not passing through the origin.

• A straight line through the origin.
