A `0.5m` long solenoid has `500` turns and has strength of magnetic field of `2.52xx10^-3T` at its center. Find the current in the solenoid.

Answer

`2*0A`

Explanation

Here, `l=0*5m`, `N=500`, `B=2.52xx10^-3T`,
`B=(mu_0NI)/(l)` or `I=(Bl)/(mu_0N)=((2*52xx10^-3)xx0*5)/((4pixx10^-7)xx500)`
`=2*0A`
