How to Use the Magnet Rule

Trilu: It's very easy to attract other people and things. Firstly, you should focus your energy and conduct a rigorous self-analysis and examination. Then, you need to carefully observe the environment around you, see how it fits in with you, and how you attract the beautiful things in life to yourself. Of course, there are also some things around you that you dislike and dislike, but how do they come to you? You also have to take responsibility for these things, it is precisely because of certain mistakes and omissions in your thoughts that these things appear in your life. Think about it, what exactly is this mistake? What action should you take against it?Bambi Lu: Being a person requires constant reflection. You should think about how the current situation is related to something in my heart; You also have to imagine yourself without hesitation as the designer and implementer of your own life and life. And your life and destiny are definitely determined by your own way of think

Suction cup electromagnet

Suction cup electromagnet, also known as lifting electromagnet, is a new type of practical magnetic lifting equipment with strong practicality; When lifting and transporting materials, there is no need to bundle or handle scattered materials, so it is also known as a bulk lifting electromagnet, which is very suitable for lifting and transporting scattered scrap steel, waste, etc.The suction cup electromagnet is based on the principle of electromagnet conversion, generating strong electromagnetic attraction in the energized state to control the forward or stop state of the object. The electromagnet has a reasonable and compact structure, with the coil placed in a soft magnetic material shell and sealed with epoxy resin. It has the characteristics of small volume, high suction, firmness, reliability, full sealing, and strong environmental adaptability. This series of electromagnets can be remotely operated, with simple and sensitive actions, and stable and reliable functions.It can be wi

Principle of Battery Magnetic Force

1. The visionary attempts to use gravity as the driving force, but does not consider the influence of gravity on the small magnet. The position of the small magnet under gravity does not exhibit a symmetrical state.2. By calculating the torque of the system, it is shown that if M=0, the runner stops at a certain position and will not continue to move.3. According to the First law of thermodynamics of thermodynamics, Q=△ E+A, part of the heat absorbed by the system is converted into the internal energy of the system, and part is converted into the external work of the system. During the entire hypothetical motion process, if the magnet repels and pushes the compression spring, it will consume energy, and if the spring returns, it will release energy. The center of gravity of the system remains unchanged, and gravity does not do work. There is no energy change in the overall process, Δ E=0. If there is no external absorption of heat Q, then (A=0) cannot do external work. So this device c

Problems in China's Soft Magnetic Materials Industry

Throughout the years of development of magnetic materials in China, the main reasons for achieving such achievements are the expansion of production scale and investment in production hardware. There is still a certain gap between the technical performance level of mass-produced magnetic products and the international advanced level. The prices of mid to low end products compete on the profit free edge, disorderly and irregular. The development of magnetic products in high-tech application fields is not strong enough for enterprises, and they cannot first occupy new application fields. In the domestic equipment manufacturing industry, there is no update and innovation in accordance with the production needs of new magnetic products, and high-end material manufacturing equipment relies on the introduction. The gap between China's magnetic materials and foreign countries is specifically manifested in the following aspects: (1) There is a gap in product quality level. The research lev

Magnetic motor

Although it negates the possible theory of Perpetual motion, it does not rule out the magnetic machine formed by the experimental arrangement of permanent magnets. If permanent magnets are properly arranged through experiments and can cause the machine shaft to move under the repulsion or attraction of the two stages of the magnet (magnetic force doing work), it is entirely possible to form a magnetic motor.Nowadays, there are many methods to achieve the manufacturing of magnetic motors, and many people have already achieved success. However, this kind of magnetic machine does not belong to "Perpetual motion", because it is constantly consuming magnetism and will always stop doing work at one time, so the magnetic machine needs to be magnetized every other period.For example, the Sel machine is also a type of magnetic machine, and there have been continuous imitators making similar Sel machines. Official research institutions in the United States and Russia are also replicating and con

Magnetic Selection Factors

Power JourneyThe stroke refers to the distance between the sliding rod position of the suction cup electromagnet and the fully closed position, and the electromagnet will generate different forces at different strokes; Generally, the smaller the stroke, the greater the force.response timeThe time from the electrification of the electromagnetic iron to the end of the expected displacement of the sliding rod.Cyclic loadCycle load=[power on time/(power on time+power off time)] × 100. Electrification of an electromagnetic iron generates heat, so the periodic negative core and the longest electrification time determine the temperature rise of the electromagnet. The temperature rise of the electromagnet and the ambient temperature determine the selection of the insulation level of the electromagnetDiode rectificationIf the suction cup electromagnet uses an AC power supply, a rectifier needs to be used to convert AC to DC; The rectifier should be designed as a full band rectifier in principle
