A solenoid of length 0.5m and diameter 0.6cm consists of 1000 turns of fine wire carrying a current of 5×10^–³ ampere.the magnetic field in Weber/ m² at the ends of solenoid will be??

The magnetic field near the ends is B=$ni/2 ( I have used $ as mu) , from the given information, we can put the values of $,n,i and on solving it gives as 31.4x10^-7 .....The value of $ is 4pi X 10^-7

Approved
