MHT CET · Physics · Magnetic Effects of Current
A circular arc of radius 'r' carrying current 'I' subtends on angle \(\frac{\pi}{16}\) at its centre. The radius of a metal wire is uniform. The magnetic induction at the centre of
cirçlar arç is
- A \(\frac{\mu_{0} \text { I }}{16 r}\)
- B \(\frac{\mu_{0} \text { I }}{32 r}\)
- C \(\frac{\mu_{0} I}{64 r}\)
- D \(\frac{\mu_{0} \text { I }}{8 r}\)
Answer & Solution
Correct Answer
(C) \(\frac{\mu_{0} I}{64 r}\)
Step-by-step Solution
Detailed explanation
\(B_{a t 0}=\frac{\mu_{0} I}{4 \pi \varepsilon}\left(\frac{\pi}{1}\right.)\)
\(B_{a t 0}=\frac{\mu_{0} I}{64 \varepsilon}\)
\(B_{a t 0}=\frac{\mu_{0} I}{64 \varepsilon}\)
