Eccentric Eddy Current

Eccentric eddy current sorting machine

The working principle of the eccentric eddy current is the same as that of the eddy current sorting machine. When materials containing non-ferrous metals have passed through the sorting drum at a certain speed, eddy currents will be induced inside the non-ferrous metals. The magnetic field generated by the eddy currents, Contrary to the direction of the internal magnetic field of the eddy current separation magnetic roller, the two magnetic fields have the same magnetic poles, so the non-ferrous metal copper and aluminum will be ejected along the conveying direction due to the repulsive force of the magnetic field.

Electric eddy current has a magnetic effect, and the changing magnetic field will generate an electric field in the surrounding space. Electromagnetic induction phenomenon abounds in life, such as audio, telephone, electric motor, induction cooker, mobile phone Bluetooth, generator and so on. It can be said that our daily life. It is inseparable from electricity and magnetism. The changing magnetic field will excite an electric field in the surrounding space.

This electric field is called an induced electric field (vortex electric field). According to the definition of electromotive force and Faraday’s law of electromagnetic induction, the induced electromotive force in the loop is equal to the line integral of the induced electric field along this closed path. Therefore, when the metal is in a changing magnetic field or moves in a magnetic field, it will be A vortex electric field appears. The free electrons in the metal move under the action of the vortex electric field to generate an induced current, and the induced current closes by itself inside it to form a vortex shape, so it is called an eccentric eddy current, or eddy current for short.

When there is a current in the conductor, the conductor will generate heat accordingly. When the resistance of the conductor is very small and the current passing through the conductor is large, the heat generated can be very large. The induction cooker in life applies this principle.

Electric current machine is used to generate a magnetic field through the coil. When the magnetic field lines in the magnetic field pass through the bottom of the metal vessel, numerous small eddy currents are generated, which makes the vessel itself heat at high speed, and then heats the food in the vessel. The ceramic surface of the stove top does not heat up, and the pot heats up by itself, and the food in the pot is cooked. The temperature can be as high as 240 degrees. The thermal efficiency of the induction cooker is extremely high, and it is safe, clean, no fire, no smoke, no exhaust gas, no fear of wind, no explosion or cause gas poisoning when cooking.

When the lines of magnetic force in the magnetic field pass through non-metallic objects, no eddy current is generated, so no heat is generated. The stove surface and people are non-metallic objects, which do not generate heat, so there is no danger of being burned by the induction cooker, and it is safe and reliable. The metal detector uses a coil through which alternating current passes to generate a rapidly changing magnetic field. This magnetic field can induce eddy currents inside metal objects.

The eddy current can generate a magnetic field, which in turn affects the original magnetic field, causing the detector to beep. The lower the working frequency, the better the detection performance of iron; the higher the working frequency, the better the detection performance of high carbon steel. The sensitivity of the detector decreases as the detection range increases, and the size of the inductive signal depends on the size of the metal particles and the conductivity. When the closed conductor and the magnetic pole cut the magnetic lines of induction, the closed conductor will generate an induced current due to the change in the magnetic flux penetrating through the closed conductor. The magnetic field generated by this current will hinder the relative movement of the two.
