The force exerted on a current-carrying wire located in an external magnetic field is directly proportional to which of the following?
A) field strength
B) current strength
C) both A and B
D) None of the above are valid.

Question

Quizplus · Accepted Answer

The force on a current-carrying wire in a magnetic field is given by F = BIL sin(θ), where B is the magnetic field strength, I is the current, and L is the length of the wire. Thus, it is directly proportional to both the field strength and the current strength.
