What is the net force on the square coil? 
- A moving towards wire
- B moving away from wire
- C moving towards wire
- D moving away from wire
Answer & Solution
Correct Answer
(A) moving towards wire
Step-by-step Solution
Detailed explanation
Force due to straight wire on the current-carrying coil is, F=FAB+FBC+FCD+FADFBC and FAD are equal and opposite therefore will cancel each other effect FAB=μ02 A1 A15×10-2 m2π2×10-2 mFCD=-μ02 A1 A15×10-2 m2π0.12 mNet force on the square coil ABCD is, F=μ02 A1 A15×10-2 m2π2×10-2…
