AP EAMCET · PHYSICS · Magnetic Effects of Current
A loop of flexible conducting wire lies in a magnetic field of \(2.0 \mathrm{~T}\) with its plane perpendicular to the field. The length of the wire is \(1 \mathrm{~m}\). When a current of \(1.1 \mathrm{~A}\) is passed through the loop, it opens into a circle, then the tension developed in the wire is
- A \(0.15\ N\)
- B \(0.25\ N\)
- C \(0.35\ N\)
- D \(0.45\ N\)
Answer & Solution
Correct Answer
(C) \(0.35\ N\)
Step-by-step Solution
Detailed explanation
Let the tension developed is \(\mathrm{T}\). Let radius of loop be \(r\). For smaller element…
