Electromagnetism Experimental Skills Quiz

What is the purpose of zeroing the balance before starting the experiment with the square loop of wire?

• To calibrate the magnet

• To avoid systematic errors

• To ensure the wire is at the correct angle

• To measure the initial current

How is the magnetic flux linkage calculated using a search coil and a magnet?

• By dividing the emf by the time interval

• By measuring the resistance of the coil

• By multiplying the emf by the time interval

• By adding the emf and the time interval

Why is it important to use an AC power supply in transformer experiments?

• To prevent overheating of the coils

• To allow the magnetic flux linkage to change

• To reduce the voltage in the primary coil

• To ensure the current remains constant

What happens when you vary the number of secondary turns in a transformer experiment?

• The secondary current remains constant
