Question

In an iron cored coil , if the iron core is removed how will it affect the inductance of the coil?

• A. the inductance will increase
• B. the inductance will decrease
• C. the inductance remains the same
• D. the inductance increases and then decrease after a time

Answer 1

The correct option is B

the inductance will decrease

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