Challenge Problems
Push your limits with challenges.
Question 1
A rectangular loop with dimensions 0.2 m x 0.4 m carries a current of 3 A in a uniform magnetic field of 0.5 T. Calculate the maximum torque the loop can experience when oriented at the optimal angle.
💡 Hint: Don’t forget to calculate the area of the loop first!
Question 2
If the same loop is now tilted to an angle of 60 degrees, what is the torque experienced by the loop?
💡 Hint: Calculate sin(60) carefully, it's a common angle!
