The magnitude of magnetic fields at a distacne 'r' from the centre of a short bar magnet, in longitudinal position to transverse position is in the ratio
- A 4:1
- B 2:1
- C 1:4
- D 1:2
Answer & Solution
Correct Answer
(B) 2:1
Step-by-step Solution
Detailed explanation
For longitudenal positions magnetic field will be \(B_{1} \alpha \frac{2 M}{d^{3}}\)
For transverse positions magnetic field will be \(B_{2} \alpha \frac{M}{d^{3}}\)
\(\therefore \frac{B_{1}}{B_{2}}=2: 1\)
For transverse positions magnetic field will be \(B_{2} \alpha \frac{M}{d^{3}}\)
\(\therefore \frac{B_{1}}{B_{2}}=2: 1\)
