Challenge Problems
Push your limits with challenges.
Question 1
A rectangular loop of size 0.1 m x 0.2 m is carrying a current of 4 A and is in a magnetic field of 0.8 T at an angle of 30 degrees. Calculate the torque acting on the loop.
π‘ Hint: Make sure to evaluate sin(30Β°) correctly.
Question 2
If we have multiple turns of wire in the loop, say 50 turns, and the same 0.1 m x 0.2 m loop area, with 2 A current, what would the torque be?
π‘ Hint: Many small loops add their effects together!
