Challenge Problems
Push your limits with challenges.
Question 1
A loop of wire has an area of 0.5 m^2 and is placed in a magnetic field of strength 0.2 T. If the field decreases down to 0 T in 5 seconds, what is the induced EMF?
💡 Hint: Remember the formula for induced EMF with the area and time taken for change.
Question 2
A transformer has 200 turns on the primary coil and 50 turns on the secondary. If the primary voltage is 120 V, what is the secondary voltage? What happens if all turns are reversed?
💡 Hint: Use the relationship between turns and voltage in transformers!
