Question

A long solenoid of length L has a mean diameter D. It has n layers of winding of N turns each. If it carries a current i, the magnetic field at its centre will be (A) proportional to D (B) inversely proportional to D (C) independent of D (D) proportional to L

Tardigrade Admin · Accepted Answer

Magnetic field due to solenoid is independent of diameter (Because B=μ0 n i )

Q. A long solenoid of length $L$ has a mean diameter $D$ . It has $n$ layers of winding of $N$ turns each. If it carries a current $i$ , the magnetic field at its centre will be

proportional to D

inversely proportional to D

independent of D

proportional to L

Magnetic field due to solenoid is independent of diameter (Because $B = μ_{0} ni$ )
