how can the self inductance of a given coil having N number of turns, area of crossection A and length - Physics - Electromagnetic Induction

Question

how can the self inductance of a given coil having N number of
turns, area of crossection A and length l be increased

Neha Gupta · Accepted Answer

When we insert the dielectric slab in the coil, then permeability
of the material increases hence its self inductance increases
