Two metallic rings A and B, identical in shape and size but having different resistivities ρA and ρB, are placed on top of two identical solenoids. When an identical current I is switched on in both solenoids, rings A and B jump to heights hA and hB respectively, with hA > hB. What is the possible relation between their resistivities and masses mA and mB?
