Answer:

Strength of Magnetic Field produced by passing current in a solenoid is inversely proportional to Total Length(L) of Solenoid.

Explanation:

What is a Solenoid?

A solenoid is a coil that is wrapped around a soft iron core and when current is applied to the coil, it behaves like an Electromagnet. The term is given by André-Marie Ampère in 1823.

Let the number of turns of coil in a solenoid be N, it's total length be L and current passing through it be I. Then, Magnetic Field B would be :

B = (μ₀IN)÷L or B∝L

where μ₀ = Magnetic Permeability of the coil.

Therefore, from above information, we can conclude that Magnetic field is inversely proportional to Length.
