<p>A compound electrical device includes a first mobile device and a second mobile device. The first mobile device includes: a first electromagnet, generating a first magnetic pole; and a first monitor. The second mobile device includes: a sensor, detecting the first magnetic pole and generating an enable signal; a second electromagnet, generating a second magnetic pole opposite to the first magnetic pole according to the enable signal; and a second monitor. The first mobile device is coupled to the second mobile device via attraction of the first and second magnetic poles.</p> |
