PHY 102 Last Minute Prep Objective Question

Question

F = BIL can only be used if magnetic field and electric current are
Options
A at right angles to each other
Correct Answer
B in same direction
C anti-parallel to each other
D anti-perpendicular to each other
Correct Answer

Option A is the correct answer.

Detailed Explanation

F = BIL sinθ. The formula F = BIL is the maximum force when sinθ = 1, i.e., when the current and magnetic field are perpendicular (at right angles).

Hint

When is the force on a current-carrying conductor maximum?
