Question
In which condition is the magnetic force acting on a given current-carrying rod placed in a magnetic field maximum and in which condition would the magnetic force not act on the rod?
✓
Answer
- $(1)$ When the direction of the electric current passing through the rod is perpendicular to the direction of the magnetic field, maximum force is exerted on the rod.
- $(2)$ When the direction of the electric current is the same as that of the magnetic field or is opposite to that of the magnetic field, no force is exerted on the rod.
