Consider a solenoid with 0.3 T magnetic field inside it. 8 cm long wire placed inside the solenoid perpendicular
Find the magnetic force acting on a to its axis if the wire carry 10 A current:
detailed solution
Correct option is B
F = I lB sinθ Here, θ=90∘, I=10A, I=8 cm = 8 × 10−2 m, B = 0.3 T∴ F = 10 × 8 × 10−2 × 0.3× sin90∘ = 0.24 NTalk to our academic expert!
