Ratio of magnetic intensities for an axial point and a point on broad side-on position at equal distance d from the centre of magnet will be or The magnetic field at a distance d from a short bar magnet in longitudinal and transverse positions are in the ratio

Options

A. `1:1`
B. `2:3`
C. `2:1`
D. `3:2`

Answer

C

Explanation

`B_(1)= (mu_(0))/(4pi).(2M)/(d^(3)), B_(2)= (mu_(0))/(4pi) .(M)/(d^(3))`
`therefore |(B_(1))/(B_(2))|= 2:1`
