dc electromagnet, the presence or absence of electromagnet magnetic field can be controlled by on and off current, dc electromagnet includes iron core, armature mechanism, excitation coil (L), and excitation coil (L) is wound on the iron core.
The dc electromagnet includes an iron core, an armature mechanism, an excitation coil (L), and the excitation coil (L) is wound on the iron core. The characteristics of the dc electromagnet are: the excitation coil (L) is connected in series with a positive temperature coefficient thermistor (RT). Then connect to the DC power supply (DCV). The utility model can save a lot of electric energy in use.
dc electromagnet has many advantages:
The presence or absence of the magnetic field of the dc electromagnet can be controlled by on and off the current; the strength of the magnetic field can be controlled by the strength of the current or the number of turns of the coil (or control the size of the iron core); the magnetic pole of the dc electromagnet can be changed by changing the direction of the current. control, etc. That is, the strength of the magnetic field can be changed, the presence or absence of the magnetic field can be controlled, the direction of the magnetic poles can be changed, and the magnetic field can disappear due to the disappearance of the current.
