What is the magnitude of the equatorial and axial fields dut to a bar magnet of length 5.0 cm at a distance of 50 cm from its mid - point ? The magnetic moment of the bar magnet is `0.40Am^2` .

Text Solution

Verified by Experts

`B_E=(mu_0m)/(4pir^3)=(10^(-7)xx0.4)/((0.5)^3)=(10^(-7)xx0.4)/(0.125)=3.2xx10^(-7)T`
`B_A=(mu_02m)/(4pir^2)=6.4xx10^(-7)T`
