Question

1 Fill in the blank:
The strength of the magnetic field .........., if the number of tung
increased in a solenoid​

Answer 1

$\huge{\boxed{\rm{\red{Answer:}}}}$

$\huge{\rm{\blue{Increases}}}$

Explanation:

The magnetic field of a solenoid is directly proportional to both current and number of turns in the solenoid.

A coil of wire which is designed to generate a strong magnetic field within the coil is called a solenoid. Wrapping the same wire many times around a cylinder creates a strong magnetic field when an electric current is passed through it. N denotes the number of turns the solenoid has. More the number of loops, stronger is the magnetic field.
