Question

26. (i) How does the magnetic field produced by a solenoid vary with the current
​

Answer 1

$\huge \underbrace \mathtt\pink{Answer}$

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.

Answer 2

Answer:

if current is increased then magnetic field also increased. if current is decreased then magnetic field also decrease.
