Application in traditional industry
In the story of magnetic materials, magnetic source, electromagnetic induction, magnetic devices, we have mentioned some of the practical applications of magnetic materials. In fact, magnetic materials have been used in a wide range of applications in all aspects of traditional industry.
For example, without magnetic materials, electrification would have been impossible because generators are used for power generation, transformers for power transmission, electric motors for electrical machinery, and loudspeakers for telephones, radios, and televisions. Numerous instruments and meters are used in magnetic steel coil structures.
Question 2: What is the role of magnets The role of magnets is too much to count

3, to do the electromagnetic relay
4, generators
5, electric motors
6, loudspeakers
7, heat treatment
8, nuclear magnetism. *** vibration can diagnose abnormal tissue in the human body, to determine the disease
9, electric fans
10, magnetic therapy pillow, magnetic therapy belt
11, with magnets made of iron remover can be removed from the flour and other iron may exist
12, magnetized water can prevent boiler scaling
13, magnetized seeds can be made to a certain extent, crop Increase
14, magnetic therapy
15, rocks of different geological ages often have different magnetic properties. Therefore, according to the magnetism of the rock to assist in determining the changes in geological age and crustal changes.
16, magnetic mineral processing
17, magnetic materials in the military field has also been widely used. For example, ordinary mines or mines can only be exploded in contact with the target, so the role is limited. And if the mine or mine on the installation of magnetic sensors, as tanks or warships are made of steel, in their proximity (without contact with the target), the sensor can detect changes in the magnetic field to make mines or mines to explode, improve the lethality
18, in modern warfare, air control is one of the keys to victory in the battle. However, the aircraft in the flight process is easily detected by the enemy's radar, and thus has a greater danger. In order to avoid enemy radar monitoring, can be coated with a special layer of magnetic material on the surface of the aircraft - wave-absorbing material, which can absorb the electromagnetic waves emitted by the radar, making the radar electromagnetic waves rarely reflect, so the enemy radar can not detect the radar echo, can not find the aircraft, which makes the aircraft to achieve the purpose of stealth. This is the famous "stealth aircraft". Stealth technology is currently the world's military research in the field of a major hot spot. The U.S. F117 stealth fighter is an example of the successful use of stealth technology.
19, in the U.S. "Star Wars" program, there is a new type of weapons "electromagnetic weapons" development research. Traditional artillery is to use the instantaneous expansion of the ammunition explosion generated by the thrust of the shell quickly accelerated, out of the gun. On the other hand, an electromagnetic cannon puts the shell in a solenoid, energizes the solenoid, and the magnetic field generated by the solenoid generates a huge push force on the shell, which shoots it out. This is called an electromagnetic cannon. Similarly, there are electromagnetic missiles and so on.

Question 5: What are the roles of magnets in daily life? 1 The simplest thing is a compass
2 A screwdriver with a magnet head can suck in screws, and it's very easy to use
3 Magnet whiteboards, something that is often used in small group lectures.
4 Speakers for speakers can't be made without magnets.
5 Electric motors
Question 6: What are the properties of magnets? What are the uses of magnets? Properties of magnets:
Magnets are magnetic and can attract ferrous objects;
2. Magnets also have poles, which are divided into N-pole and S-pole
Magnets are used in the following areas:
1. Motor field: VCM, CD, DVD-ROM, wind generator, electric motors, servo motors, micromorphic motors, motors, vibratory motors, etc.
2.

I hope that my answer can help you!
Question 7: What are the uses of iron absorbers? There are two kinds of things that can be called iron absorbers, which are roughly referred to as iron absorbers and electromagnets.
One is natural or man-made and always has an attraction to iron, and the other is man-made and acquires magnetism by passing electricity around the iron core.
Iron absorbers are always magnetic and can be used to sense other magnetic fields, such as to make a compass or something like that, and the good thing about this kind of thing is that it works all the time and doesn't consume anything.
An electromagnet has to be energized to be magnetic, and although there is a consumption of electricity, we can then control when to make it magnetic, such as making a weightlifter out of an electromagnet, and also the consumption of electricity can be used as a signal for measurements, such as for minesweeping.
Question 8: What objects in our daily lives are equipped with magnets? What is the role? 1: headphones This needless to say, speakers used on the speaker, with neodymium-iron-boron or ferrite magnets do
