An electromagnetic attachment apparatus includes a power supply, an electromagnet module, and a rotatable module. The electromagnet module includes a coil and a core positioned in the coil. A mounting panel is attached to the core. A pair of electrically conductive blocks is attached to the mounting panel, and connected to the coil. The rotatable module is rotatably attached to the mounting panel, and includes a pair of electrically conductive pins connected to positive and negative electrodes of the power supply respectively. The rotatable module is rotatable to a first position in which the electrically conductive pins thereof contact the electrically conductive blocks for attaching a metal object, or a second position in which the electrically conductive pins thereof disengage from the electrically conductive blocks for releasing the metal object. |
