Challenge Problems
Push your limits with challenges.
Question 1
If a straight wire carrying a current of 6 A is placed in a magnetic field of uniform strength, how would the angle of the wire with respect to the magnetic field affect the force experienced by the wire?
💡 Hint: Think about the right angles maximizing the force.
Question 2
Design an experiment to compare the strength of the magnetic fields produced by a straight wire and a circular loop. What results would you expect?
💡 Hint: Consider how the shape of the conductor influences the magnetic field.
