Question

A wire of length 2.5m carrying a current of 1.3A is inclined at an angle θ to the direction field of value 0.4 T. Calculate the value of θ if the force on the wire is 0.92N.
Options
A 15°
B 30°
C 45°
Correct Answer
D 55°
Correct Answer

Option C is the correct answer.

Detailed Explanation

F = BIL sinθ => sinθ = F/(BIL) = 0.92/(0.4×1.3×2.5) = 0.707 => θ = 45°.

Hint

Use F = BIL sinθ and solve for the angle.
