A current of 10 A is flowing in a wire of length 1.5 m. When placed in a uniform magnetic field of 2 T, it experiences a force 15 N. The angle between the magnetic field and the direction of flow of current is
- A \(60^{\circ}\)
- B \(30^{\circ}\)
- C \(90^{\circ}\)
- D \(0^{\circ}\)
Answer & Solution
Correct Answer
(B) \(30^{\circ}\)
Step-by-step Solution
Detailed explanation
\(F = BIL \sin\theta\) \(15 = (2)(10)(1.5) \sin\theta\) \(\sin\theta = \frac{15}{30} = 0.5\) \(\theta = 30^{\circ}\)
