Question

No force works on the conductor carrying electric current when kept ?

Answer 1

Answer:

when the conductor is placed perpendicular to the magnetic field then no force acts .

Explanation:

if theta = 90°

then ,

F = Bil costheta

= Bil × cos 90°

= Bil × 0

= 0

Answer 2

F = i(LxB)
= iLBsinθ
If F=0
Then sinθ=0
=> θ=0
Therefore conductor experiences no force when placed along/parallel to the magnetic field(B).
