Abstract

The utility model relates to an electromagnetic device, which contains a base(1), and a compression spring(2) located on the said base, and the first electromagnet(31) located on the compression spring. The device also includes a frame(4), and two second electromagnets (32, 33) and a third electromagnet (34) attached on the said frame. The two second electromagnets are placed on both sides of the first one and are separately connected to the pull rod (61, 62) with the base. The third electromagnet is placed on top of the first one. The polarity (N1, N3) of the pole on both sides of the upper and lower part of the first electromagnet, and the polarity (N2) of pole of the second electromagnet facing towards the first one, and also the polarity (N4) of the pole of the third electromagnet facing the first one are all the same, either all are N pole or all S pole. Hence, this present electromagnetic device can produce interaction force between the magnetic field of the first electromagnet, the second ones and the third one.
