TS EAMCET · Physics · Magnetic Effects of Current
A semi-circular loop of radius \(30 \mathrm{~cm}\) wire carries current \(6 \mathrm{~A}\). An uniform magnetic field \(0.5 \mathrm{~T}\) is present perpendicular to the plane of the loop. What is the magnitude of force exerted on the wire?
- A \(0.9 \mathrm{~N}\)
- B \(1.8 \mathrm{~N}\)
- C \(0.8 \mathrm{~N}\)
- D \(1.4 \mathrm{~N}\)
Answer & Solution
Correct Answer
(B) \(1.8 \mathrm{~N}\)
Step-by-step Solution
Detailed explanation
Given, the radius of a circular loop, \[ R=30 \times 10^{-2} \mathrm{~m} \] current, \(I=6 \mathrm{~A}\) and magnetic field, \(B=0.5 \mathrm{~T}\). Force exerted on the wire,…
