“Variable Inductance Coil“

Product description

“Variable Inductance Coil. No investigation into electromagnetic theory is complete without measuring the inductance and self-inductance of a current-carrying coil (depending on the insertion of an iron core) and exploring AC circuits. Copper wire coil features a shock-resistant plastic casing with lifting handles, a coated iron core mounted on a worm screw for moving in and out of the coil, and a scale printed in cm for reading the length of core inserted into the coil.Features:Number of windings: 3000Max. permissible voltage: 30 V AC, 60 V DCMax. permissible current: 2 AInductance: continuously adjustable from 0.15 to 1.4 H, for current of apProximately 1 AResistance: 12.5 OConnections: via 4-mm safety plugs“
