Abstract: A restraining device comprised of electromagnets attached to a structure and steel pieces attached to a person's wrists that are controlled to restrain or release a person. This restraining device is wired to an enclosure with various electronic components that provide many ways of activating and deactivating the electromagnets of the restraining device. For example, it could be remotely controlled by another individual over the internet, but could also be configured to be used alone for self-restraint. A plurality of safety mechanisms, including a panic button, a countdown timer, a network polling mechanism and voice control can all be applied to make it possible for the person who is using this device to be released from their restraints.
