A solenoid of length 1 m has radius 1 cm and is made up of 1000 turns. It carries a current of 5 A. What is the magnitude of magnetic field inside the solenoid? (Take, `mu_(0)=4pi xx 10^(-7)`)

Explanation

We know that,
`B=mu_(0)nI`
Given `mu_(0) =4 pi xx 10^(-7) , n=1000` turns,
`I=5A`
Thus, `B=4pi xx 10^(-7) xx (1000)/(1) xx 5`
`=62.8 xx 10^(-4)T`
`=6.28 xx 10^(-5)T`
