Used to demonstrate that how electric energy is converted into a very strong magnetic field. The precision machined contact surface makes this electromagnet so strong that it generates tremendous lifting power. The electromagnet is consists of core and yoke with vertically fitted four ‘D’ type cell holders around the electromagnet. The core has a cylindrical coil wound with enameled copper wire on annular insulated bobbin. It can also be operated with 6V/2Amp DC power supply.
