Calculate the magnetic induction at a point 1 away from a proton, measured along its axis of spin. The magnetic moment of the proton is `1.4xx10^(-26)A-m^(2)`

Explanation

Considering the loop as a short dipole .
`B_("axial") = (mu_(0))/(4pi) xx (2M)/(r^(3))`
`= (10^(-7) xx 1.4 xx 10^(-26) xx 2)/((1 xx 10^(-10))^(3))`
`= 2.8` mT .
