6. Magnetic lifting equipment

6.1 Definition. Description

A lifting electromagnet is a handling device used to pick up ferromagnetic materials.

A magnetic current flowing through the electromagnet coil creates a magnetic field, which in turn generates a magnetic force to grip, hold and handle the ferromagnetic load (figure 13 ).

A lifting electromagnet consists of :

• one or more coils ;

• a carcass with a protective shield (mainly for mechanical protection);

• insulation with a terminal box ;

• suspension components....
