Abstract
A holding tool to handle a first permanent magnet in a stack of permanent magnets is provided. The holding tool comprises a body including a holding portion including an electromagnet, and a switch disposed on the body and electrically connected to an electrical circuit of the electromagnet and configured to energize the electromagnet by connecting the electrical circuit and de-energize the electromagnet by disconnecting the electrical circuit. The holding portion includes a hollow member made of ferromagnetic material and a coil surrounding the hollow member to form the electromagnet and the electromagnet is configured to, when energized in a first current direction, have a polarity opposite to a polarity of the permanent magnets in the stack.
