📝 Practice Problems
- A 20 cm by 30 cm rectangular loop of wire carries 1.0 A of current clockwise around the loop. Find the magnetic force on each side of the loop if the magnetic field is 2.5 T in a direction parallel to the area vector of the loop. What is the net magnetic force on the loop?
✅ Partial Solutions
- Top and bottom: 0.75 N; Left and right: 0.5 N; There is no net magnetic force.
