A uniform magnetic field of `0.20 xx 10^(-3) T` exists in the space. Find the the change in the magnetic scalar potential as one moves through 50cm along the field.

Explanation

Since `B = - (dv)/(dl)`
`dv = B dl`
`= - 0.2 xx 10^(-3)xx 0.5`
`= - 0.1 xx 10^(-3)Tm`
here -ve shown that the potential decreases
