Explanation:
Calculate the inductance of a ring-shaped coil having a mean diameter D = 200 mm wound on a wooden core of diameter d = 20 mm.
The winding is evenly wound and contains 500 turns. If the wooden core is replaced by a ferromagnetic core which has a relative permeability of 600 when the current is 5 A, calculate the new value of inductance.
[Hint: compute inductance length as π D (m) and area as π d^2 (m^2 )]
