Abstract
A connection/disconnection method, including detecting, by an electronic device, a change of a magnetic flux of a first magnetic field in the electronic device, generating a first electric signal according to the change of the magnetic flux, where the first magnetic field is generated by an electronic component, a magnetic force of the first magnetic field is used to drive the electronic component to be connected to the electronic device, determining, by the electronic device, whether identification information of the target connection component is the same as a preset identifier when a change of the first electric signal meets a first preset model, and driving, by the electronic device, the electronic component to be disconnected from the electronic device when the identification information of the target connection component is different from the preset identifier.
