Question

When an electric current is flowing through a wire, the force deflecting the charged particles is greatest when the wire is _________ to the magnetic field.
A) parallel
B) diagonal
C) perpendicular
D) at a 30° angle

Answer 1

(c) Perpendicular will be the correct option .

because we know that force on a current carrying wire of length say 'L' when placed in a magnetic Field say 'B' is given by...

F = i(L×B) = iLB sin∅

Thus force will be maximum only when ∅ = 90° .
