Demonstrates how electric current can
be used to generate very strong magnetic fields. This two part, dissectible
electromagnet comprises a core and yoke with their mating surfaces precisely
machined to very close tolerances. The core has a cylindrical coil wounded with
enameled copper wire on annular insulated bobbin with both ends of winding
terminating in crocodile clips. Back of the core has a cell holder that can be
connected to coil using crocodile clips. Both core and yoke provided with steel
eye-bolts. Generate tremendous lifting power.
