MHT CET · Physics · Magnetic Effects of Current
A straight wire of length \(0 \cdot 5 \mathrm{~m}\) and carrying current of \(1 \cdot 2 \mathrm{~A}\) is placed in a uniform magnetic field of induction \(2 \mathrm{~T}\). The magnetic field is perpendicular to the length of the wire. What is the force acting on the wire? \(\left[\sin 90^{\circ}=1\right]\)
- A \(2 \cdot 0 \mathrm{~N}\)
- B \(2 \cdot 4 \mathrm{~N}\)
- C \(1 \cdot 2 \mathrm{~N}\)
- D \(3 \cdot 0 \mathrm{~N}\)
Answer & Solution
Correct Answer
(C) \(1 \cdot 2 \mathrm{~N}\)
Step-by-step Solution
Detailed explanation
