What is the formula for the magnetic field due to a solenoid?(a) μnI(b) μn^2(c) μNI(d) μN^2I^2This question was addressed to me in unit test.I'm obligated to ask this question of Magnetic Field of a Solenoid topic in section Electromagnetism of Basic Electrical Engineering

Answer»

Correct answer is (a) μnI

The best I can explain: The MAGNETIC FIELD due to a solenoid is:

B= μnI, where μ is the permeability, n is the NUMBER of turns per unit LENGTH and I is the CURRENT in the solenoid.
