Question

A long solenoid has 200 tums per cm
and canies a current'i. The magnetic field
at its centre is
6.28 x 10-2
Weber/m? Another long solenoid has 100
tums per
cm and it camies a curent'i/3'.
The value of the magnetic field at its centre
is
O 1.05 x 10-*Weber/m²
O 1.05 x 10-?Weber/m2
O 1.05 x10-5Weber/m?​

Answer 1

That's it I guess..............
