Abstract
The utility model provides a controllable mechanism for enhancing or weakening the magnetic field of a magnet, which comprises a first circuit and a second circuit. The first circuit and the second circuit are connected in parallel with each other. The first circuit comprises a switch connected in series with a first power supply, an adjustable resistor and an inductor. The second circuit comprises a gauss meter connected in series with a second power supply, and a second switch. One side of the inductor is provided with a to-be-machined magnet. According to the technical scheme of the utility model, the current magnitude can be adjusted by means of the adjustable resistor. Due to the adoption of the parallelly connected circuit combination, the magnetic field of the magnet can be enhanced and weakened respectively. Meanwhile, the field enhancing or weakening operation of the magnet can be accurately controlled. Therefore, the controllable mechanism can be applied to the production of precise magnetic sensors.
Description
Technical field
The utility model relates to a kind of magnet and adds the demagnetize controllable mechanism.
Background technology
Common magnet adds magnetic, generally by saturation magnetization technique, the principle that magnetizes be in coil by the direct current of constant current, make coil produce the stationary magnetic field.But the magnetic field intensity that magnet adds behind the magnetic finally still depends on the material of magnet own, is difficult to accurately the magnetize strength control in magnetic field of target magnet.
The utility model content
The purpose of this utility model is to solve above-mentioned technical problem, provides a kind of magnet to add the demagnetize controllable mechanism.
The purpose of this utility model is achieved through the following technical solutions:
Magnet adds the demagnetize controllable mechanism, includes first, second circuit in parallel, and described the first circuit comprises switch, adjustable resistance and the inductance that is connected in series with the first power supply;
Described second circuit comprises that the Gauss who connects with second source takes into account second switch, and a side of described inductance is provided with magnet to be processed.
The beneficial effects of the utility model are mainly reflected in: by adjustable resistance size of current is regulated, circuit combination by parallel connection is added and subtracted magnetic to magnet respectively, accurately the demagnetize that adds of magnet is controlled, be can be applicable to the production of accurate magnet sensor.
