Challenge Problems

Push your limits with challenges.

Question 1

A current-carrying wire with a length of 3 m carries 4 A of current and is placed in a magnetic field of strength 0.5 T at an angle of 60 degrees. What is the force acting on the wire?

💡 Hint: Make sure to use the sine of the angle in your calculations.

Question 2

If a generator produces an electric current of 10 A with 5 turns of wire in a changing magnetic field, what factors can you adjust to increase the induced current?

💡 Hint: Think about how changing design variables affects inductance.
