Question

Field inside a solenoid is : (A) directly proportional to its length (B) directly proportional to current (C) inversely proportional to number of turns (D) inversely proportional to current

Tardigrade Admin · Accepted Answer

Magnetic field within the solenoid is uniform and parallel to the axis of the solenoid. Magnetic field is given by B=μ0 n i where i is current, n the number of turns. Hence, B propto i

Q. Field inside a solenoid is :

directly proportional to its length

directly proportional to current

inversely proportional to number of turns

inversely proportional to current

Magnetic field within the solenoid is uniform and parallel to the axis of the solenoid.
Magnetic field is given by $B = μ_{0} ni$
where $i$ is current, $n$ the number of turns. Hence, $B \propto i$
