Horseshoe Electromagnetic Substrate specificity of invertaseLarge Electromagnet, Dissectible, Deluxe. Designed to demonstrate the basic operation of simple electromagnets. Comprises of two coils, U shape iron core and an armature. On outmost layer of the coils are several turns of plastic coated wires, indicating the winding direction of the coil. Each of the coils has two terminals which can be connected in series or in parallel. When used on 4 6 volt, 1 Amps in parallel the armature can bear a load of more
