Question

find the magnitude of the magnetic force on the measurement PQ placed in a magnetic field of 0.25 T if a current of 5 ampere flows through it​

Answer 1

Answer:

Force on a current carrying wire is given by

F = iLBsinθ ....... (where θ is the angle between the B and L )

here in the given problem θ = 60°

∴ F = iLBsin60° = 5A x 0.3m x 0.25T x √3/2 = 0.325N

Force on PQ part of the wire = 0.325N
