Calculate the magnetic field inside a solenoid when the number of turns is halved and length of the solenoid and the area remain the same.

Text Solution

Verified by Experts

Magnetic field inside a solenoid is `B=(mu_0 NI)/L`
If the number of turns is halved `B.=(mu_0(N/2)I)/L rArr B.=1/2((mu_0NI)/L)`
