Name any three factors on which the magnitude of the magnetic field due to a solenoid depends.

(N/A) The magnitude of the magnetic field produced by a solenoid depends on the following three factors:
$(i)$ The strength of the current flowing through the solenoid: The magnetic field strength is directly proportional to the current.
$(ii)$ The number of turns (loops) in the solenoid: The magnetic field strength increases as the number of turns per unit length increases.
$(iii)$ The nature of the core material: Placing a soft iron rod inside the solenoid significantly increases the magnetic field strength due to magnetization.
