In an iron cored coil the iron core is removed so that the coil becomes an air cored coil. The inductance of the coil will

Answer & Solution
Correct Answer: Option B
In an iron cored coil, the presence of the iron core significantly increases the inductance due to the higher magnetic permeability of iron compared to air.

When the iron core is removed, the coil becomes an air cored coil, which has much lower magnetic permeability.

As a result, the inductance of the coil will decrease.

If the iron core is removed, it will reduce the magnetic field around and hence, the inductance will decrease.
