Several magnetization methods for magnets

1. DC magnetization methodDirect current magnetization method is a commonly used method for magnetizing magnets. The principle is to apply a DC voltage at both ends of the magnet to rearrange the magnetic domains inside the magnet, achieving the purpose of magnetization. This method has the advantages of simple operation, low cost, and stable effect, but the magnetization time is longer and the efficiency is slightly lower.Operation method: First, fix the magnet on the magnetization device, and then connect the DC power supply to the magnetization coil. Choose the appropriate voltage, current, and magnetization time based on the size, shape, and magnetic performance requirements of the magnet. During the magnetization process, the magnet will generate heat, so it is important to lower the temperature to prevent a decrease in the magnetic properties of the magnet.2. Pulse magnetization methodPulse magnetization method is the use of high-energy pulse current to magnetize a magnet, which

The Disadvantages of Magnets

1. Interference with medical equipmentMagnetic fields can interfere with medical equipment and affect the effectiveness of medical treatment. If patients wear magnets for treatment, it may cause interference with medical equipment such as pacemakers and artificial hearts, leading to accidents.2. Threats to human healthLong term use of magnets for treatment may have negative effects on human health, such as dizziness, nausea, and skin allergies. If the patient belongs to a group of special diseases such as hypertension and varicose veins, using magnets for treatment will worsen the condition and cause adverse reactions.3. Magnets without scientific researchAlthough magnets have been widely used in multiple medical fields, their use has not yet been scientifically studied. Further scientific experiments and research are needed to ensure the efficacy and safety of magnetic therapy, in order to ensure good treatment outcomes and patient safety.

The benefits of magnets

1. Improve blood circulationMagnetic fields can stimulate microcirculation in the human body, promote blood circulation, improve the transportation of oxygen and nutrients, thereby promoting cell metabolism, enhancing the body's immune system, and improving physical health.2. Relieve painMagnets have a great analgesic effect, which can alleviate muscle and joint pain and improve human comfort. Magnets can also have a certain therapeutic effect on pain symptoms such as rheumatoid arthritis, back pain, and headaches.3. Promote trauma recoveryMagnets are widely used in the field of wound recovery, which can reduce inflammatory reactions, promote cell regeneration and repair, and improve wound healing speed. In addition, magnets can accelerate fracture healing, reduce pain and discomfort during healing.

What is the transmission of magnetic force between magnets

As far as we know, all interactions of forces can essentially be attributed to four fundamental forces - electromagnetic force, gravity, strong nuclear force, and weak nuclear force. For example, the magnetic and contact forces (including frictional and elastic forces) that attract magnets to each other are essentially electromagnetic forces.In theory, each fundamental force is transmitted by a fundamental particle (the graviton that transmits gravity has not yet been discovered), and in the case of electromagnetic force, its transmission depends on photons. Since electromagnetic interaction exchanges photons, why can't we see the two magnets that attract each other or the light emitted when pushing an object?According to quantum field theory, photons carrying electromagnetic force are not ordinary photons, but virtual photons, and we cannot see these virtual particles that exist for an extremely short time. So, how do virtual photons transmit electromagnetic force?Virtual photons

Neodymium iron boron magnets for motors

Neodymium iron boron magnets are widely used in various types of motors due to their strong magnetic force. It can easily meet your pursuit of high speed, high torque, and high efficiency. In the magnetic environment inside the motor, it can bring you good magnetic field effects and achieve better performance of the motor.Our motor uses high-performance neodymium iron boron magnets, which are not ordinary magnets! The strong magnetic force of this magnet means higher efficiency and longer service life. It can make the motor more delicate and efficient, bringing you a better convenient experience. The advantage of neodymium iron boron magnets lies in their long-lasting durability. Neodymium iron boron magnets used in motors have high coercivity, high magnetic energy product, and good temperature stability. A good motor not only needs to be able to operate stably for a long time, but also needs to be able to maintain stability under various complex conditions.Neodymium iron boron magnets

What coatings do neodymium iron boron magnets have?

Due to the presence of iron element in sintered neodymium iron boron magnets, the coating is a very important part of neodymium magnets. Although we can offer multiple electroplating options, nickel is still the most common and usually the preferred.Nickel plated magnets actually consist of three layers of nickel plating, copper plating, and nickel plating. This three-layer electroplating makes our sintered neodymium iron boron magnets more durable than single-layer nickel plated magnets. Other coating options include zinc, tin, and rubber, epoxy resin, silver, and gold.Sintered neodymium iron boron magnets can be used in many products at room temperature and some higher temperatures up to 200 ℃. The application fields include wind energy, petroleum energy, automobiles, electronics industry, IT, healthcare, mining, audiovisual, sports, toys, stationery, printing, packaging, gift handicrafts, etc.Common shapes: discs, rings, cylinders, squares, bars, etc.Irregular shapes: arc-shaped, co
