Question
A circular coil carries current I. An insulated infinitely long wire placed along the diameter of the coil is also carrying current I. The magnetic force on the wire is
- zero
- along the wire
- perpendicular to the wire and the plane of the coil
- perpendicular to the wire and in the plane of the coil
The correct answer is: perpendicular to the wire and in the plane of the coil
.
is magnetic due to the coil and is perpendicular to its plane. Therefore, 
will be perpendicular to I as well as , which is in the plane of the coil.
