An electromagnet is a device which uses a current and passes this through a conductor. The current induces a magnetic field in the conductor, making the conductor a magnet. In order to remove the effects of this magnetism, the device may have its electrical power cut off. Therefore, the way to drop the staples in the bin would be to remove the battery.
