Question

How strength of magnetic field varies with no. of helical turns in a solenoid?​

Answer 1

$\huge \mathfrak \fcolorbox{purple}{lavender}{ANSWER}$

The field inside a solenoid is strong and uniform. The small magnetic fields caused by the current in each turn of the coil add together to make a stronger overall magnetic field. The strength of the magnetic field around a solenoid can be increased by: increasing the number of turns on the coil.
