JEE Main20249 Apr 2024Morning ShiftPhysicsMagnetic Effects of CurrentActual
A square loop of edge length 2 ~m carrying current of 2 ~A is placed with its edges parallel to the xy axis. A magnetic field is passing through the x-y plane and expressed as B =B₀(1+4 x) k , where B₀=5 ~T . The net magnetic force experienced by the loop is _______ N .
Correct answer
0
Step-by-step solution
aligned & B ( x =0)= B ₀, ~B ( x =2)=9 ~B ₀ & Also, F = i B & F ₁= i B ₀ & ~F ₂=9 i B ₀ & ~F = F ₂- F ₁=8 i B ₀=8 2 2 5 & ~F =160 ~N aligned
