Electromagnetic trigger

Abstract

The invention discloses an electromagnetic trigger. The electromagnetic trigger comprises a coil, a first magnet and a second magnet, wherein the first magnet and the second magnet are arranged side by side; the magnetization directions of the two magnets are opposite to each other; the coil is arranged between the two magnets; the two ends of the coil are positioned at the two ends of the magnets; and the current direction in the coil is variable. The electromagnetic trigger can achieve the purpose that the motion direction of the trigger and the magnetization directions of the magnets are the same through only two magnets, and realizes the side-to-side movement of the coil.

Description

technical field [0001] The present invention relates to an electromagnetic trigger. Background technique [0002] Electromagnetic triggers are used in many fields. The physical principle is that the current-carrying conductor will move under force in the magnetic field generated by the permanent magnet. One of the typical applications is the swing, as Figure 1 shown. Magnet assembly 1 is made up of magnet 1 and 2, and the magnetization direction of magnet 1 and 2 is perpendicular to the plane and the magnetization direction is opposite. The magnet assembly II is composed of magnets 3 and 4. The magnetization directions of magnets 3 and 4 are perpendicular to the plane and opposite to each other, but the magnetization directions of 3 and 1 are the same, and the magnetization directions of 4 and 2 are the same. Assemble components I and II with 3 pairs of 1, 4 pairs of 2, face to face and a certain distance apart to form a complete component. Between magnet 3 and 1 like th...
