Challenge Problems

Push your limits with challenges.

Question 1

A charged particle with charge q and mass m moves at a velocity v perpendicular to a magnetic field B. What is the radius of the circular path described by the particle?

💡 Hint: Think about how the magnetic force acts as a centripetal force.

Question 2

Consider a wire of length 1 meter carrying a current of 5A situated in a uniform magnetic field of 0.1T at an angle of 30 degrees. Calculate the magnetic force experienced by the wire.

💡 Hint: Break the force calculation into its components, considering the sine of the angle.
