Q1

A solenoid is \(2\mathrm{m}\) long and \(3\mathrm{cm}\) in diameter. It has \(5\) layers of winding of \(1000\) turns each and carries a current of \(5\mathrm{A}\). What is the magnetic field at its centre? Use the standard value of \({\mu }_{0}\).

a

\( 1.57 \times 10^{-4} \mathrm{~T} \)

b

\( 2.57 \times 10^{-3} \mathrm{~T} \)

c

\( 1.57 \times 10^{-2} \mathrm{~T} \)

d

\( 3.57 \times 10^{-6} \mathrm{~T} \)
