Answer:
Inductance of Inductor is directly proportional to permiability of the core material.
when air core inductor of inductance 20 mH becomes 80 mH means relative permeability μr = 80/20 = 4.
Relative permeability μr and susceptibility χr are related by μr = ( 1 + χr )
hence susceptibility χr = 3
