Challenge Problems

Push your limits with challenges.

Question 1

A circular loop of wire is placed in a changing magnetic field. If the magnetic flux through the loop increases at a constant rate, calculate the induced EMF if the rate of flux change is 0.5 Weber per second.

💡 Hint: Remember the formula for induced EMF.

Question 2

If a transformer steps down an input voltage of 120V to an output of 12V, what can you deduce about the number of turns in the primary and secondary coils if there are 100 turns in the primary coil?

💡 Hint: Think about how voltages relate to the number of turns in coils.
