Question

The direction of the force on a current carrying wire located in an external magnetic field is which of the following?

A) perpendicular to the current
B) perpendicular to the field
C) parallel to the wire
D) both choices A and B are valid
E) none of the above are valid
​

Answer 1

Option c

hope this helps u

Answer 2

The direction of the force on a current-carrying wire located in an external magnetic field is both choices A and B are valid

• We know that force on a current-carrying wire is given by,

$F = I(L×B)$

$F = ILBsin \alpha$

where I = current in the wire, L = length vector of the wire and B = magnetic field

• So, force is in the direction perpendicular to length vector i.e wire and magnetic field.

• Therefore option C is wrong according to the force formula.
