An apparatus for controlling a lifting cover open automatically, is applied in
an electric product with a lifting cover. The apparatus includes a first magnetic
device disposed on the main body of the electric product, a second magnetic device
disposed on the lifting cover with respect to the first magnetic device, and a
controlling device disposed on the main body for controlling switch on/off between
the first magnetic device and power of the electric product. An inducing magnetic
field is formed when the first magnetic device is connected to the power of the
electric product, and the inducing magnetic field produces a repulsive force to
the second magnetic device on the lifting cover so as to have the lifting cover
open automatically.
