Magnets of various shapes and their applications Magnets come in various shapes and sizes, such as disks, spheres, Horseshoe, and many other unique shapes. Usually, larger magnets are stronger, but now it's always the case. Small magnets can be improved to increase strength by using different materials. However, the shape of a magnet can tell you much more than its size. The shape of each magnet affects its usage. It determines the arrangement of magnetic field lines outside the magnet and their tensile strength. What are the common shapes of magnets and how to use them?Bar magnetThe force of the magnet is concentrated at both poles and weakens on both sides. A bar magnet is usually the weakest shape because the area of the magnetic pole is the smallest. However, they are the most commonly used shapes in daily life, such as refrigerator stickers and compasses.Bar magnets are also commonly used for classroom demonstrations. For example, you can use a bar magnet to display the magnetic field by spreading metal shavings on a piece o: 25

Horseshoe magnet A horseshoe shaped magnet is simply a bar magnet bent into a U-shaped shape. The U-shaped shape points the magnetic poles in the same direction, making the magnet stronger. This shape was originally created as a substitute for a bar magnet and has now become a universal symbol for magnets. According to the strength of a horseshoe magnet, it can be used to absorb metal objects of any size. For example, a small Horseshoe can collect Paper clip, while an industrial size Horseshoe magnet is used in construction and engineering to absorb large heavy metals. A horseshoe magnet is also used at the bottom of the pendulum.Disk magnetWe can manipulate the shape of the magnet to increase the magnetic pole area, thereby increasing its suction. Due to its wide and flat surface, the disk magnet has a large magnetic pole area, making it a sturdy and effective magnet.Square magnetAccording to the size of the disk, this shape has multiple uses. Disk magnets are used daily in clothing, fashion accessori: 25

How magnets generate magnetic force Do you know about magnets? A magnet is a very magical thing that can hold onto some iron objects, such as nails, keys, scissors, and so on. Are you curious why magnets have such abilities? Where does the power of a magnet come from? Will it disappear?In fact, the power of a magnet is generated by some very small things inside it. These things are called atoms, and you can imagine them as small balls, each with smaller balls spinning around. These smaller balls are called electrons, and they are like some miniature batteries that can generate electricity and magnetic fields. Each electron has a front and a back, which we call a magnetic pole.The number and arrangement of electrons in different atoms are different, so the magnetic field they generate is also different. In some atoms, the magnetic field of the electrons just cancels out, so there is no magnetism. In some atoms, the magnetic field of electrons is not completely cancelled out, so there is a bit of magnetism. In some atoms,: 23

What is the Grinding Machine Processing of Magnets What is a grinding machine for magnets? What is the working principle of a grinder processing magnet? Seeing many people asking such questions, today the magnet manufacturer Xiao Fu will share with everyone.For some magnets, grinding machines are required. Grinding machines are a type of machine tool developed to adapt to precision machining of magnets. They are a type of precision machining machine tool that uses non-metallic grinding tools or abrasives to process various surfaces of workpieces. Usually, the grinding tool revolves as the main motion, and the rotation and movement of the workpiece or the movement of the grinding tool are feed motion. Usually, machine tools that use grinding wheels for processing are called grinding machines, and chamfering machines are also a special type of grinding machine.The grinding machines of grinding machines mainly include surface grinding machines and double end grinding machines. Double end grinding machines are mainly used for grinding hard: 23

Introduction to Irregular Beveled Spiral Magnetic Tiles as the Leading Actor in the Field of Motor Energy Conservation In our daily lives, square magnets, circular magnets, cylindrical magnets, circular ring magnets, countersunk hole magnets, etc., should be familiar to everyone and often come into contact with. But some magnets, such as spiral tile magnets, should be unfamiliar to most people. Below, the magnet manufacturer will briefly introduce the irregular bevel spiral magnetic tile.Neodymium iron boron spiral magnetic tileSpiral tile magnet, also known as inclined edge tile magnet, is currently widely used in the field of energy-saving motors, injecting new energy into the energy-saving of motors.Due to its unique shape, the machining process is extremely complex. Generally, it is necessary to first draw a simulation diagram using CAD software to obtain relevant data, and then perform multiple polishing and cutting before forming.Often, processing a spiral tile magnet requires about 4 times the amount of raw material.

What is high-temperature demagnetization? Firstly, what is high-temperature demagnetization?High temperature demagnetization refers to demagnetizing a demagnetized product (neodymium iron boron magnet) in a high temperature environment. The principle is that in a high temperature environment, if the temperature is greater than the Curie temperature of the magnet and the thermal movement of the magnet molecules causes the magnetic moment to rearrange in a disorderly and disorderly manner, with different directions, and the overall external manifestation is demagnetization, which is the principle of high temperature demagnetization.What are the methods or equipment for high-temperature demagnetization of neodymium iron boron?Heating magnetThe neodymium iron boron series magnets can be demagnetized using hot oil, with an oil temperature usually reaching 80-200 degrees Celsius, which can completely eliminate magnetism. The disadvantage of using this method is that the oil film generated on the surface of the product after hot bath: 23

The main specifications of neodymium iron boron permanent magnets have a significant impact on motor performance The remanence index is the maximum magnetic flux intensity that a magnet can provide after being magnetized without an external magnetic field. The larger the value, the higher the magnetic density of the magnet's air gap, and the higher the maximum torque and efficiency point.Coercive force is a parameter that represents the ability of a magnet to resist demagnetization. The larger the value, the lower the thickness of the magnet during motor design, and the stronger the ability to resist overload;The maximum magnetic energy product represents the maximum magnetic energy that a magnet can provide to the outside world. The higher the value, the less magnets will be used at the same power.The Curie temperature Tc is the temperature point at which the magnetic properties of the magnet disappear, indicating the temperature range within which the magnet can operate.And the temperature coefficientα If it is a magnet, it represents the percentage of reversible changes in the magnetic pro: 20
