(at any angle)
So, for the equation to be true, sinθ should be equal to 1 and that is only possible when , or in other words, when the direction of electric current is perpendicular to the direction of magnetic field.
The correct option is "C"

What is a compass? How is a compass used to find directions?
Magnetic field lines never intersect each other because
There will be two directions of the field at the same point.
Feild lines repel each other
Field lines follow discrete paths only
If field lines intersect they create a new magnetic field within the existing fieldTwo parallel wires carry currents of 20 A and 40 A in opposite directions. Another wire carrying a current antiparallel to 20 A is placed midway between the two wires. The magnetic force on it will be
