COMEDK · Physics · 20. Magnetic Properties of Matter
The intensity of magnetic field due to an isolated pole of strength \(m_{p}\) at a point distant \(r\) from it will be
- A \(m_{p} / r^{2}\)
- B \(m_{p} r^{2}\)
- C \(r^{2} / m_{p}\)
- D none of these
Answer & Solution
Correct Answer
(D) none of these
Step-by-step Solution
Detailed explanation
The intensity of maznetic field due to isolated pole of strength \(m_{\mu}\) at a point distance \(r\) from it is given as \[ B=\frac{\mu_{0}}{4 \pi}, \frac{m_{p}}{r^{2}} \] Hence, no option is eorrect.
