Refers to the north and south, attracting light and small objects, electromagnets can be used as electromagnetic relays, motors, generators, electroacoustic, magnetic therapy, magnetic levitation and nuclear magnetic vibration.
food therapy
The magnet is salty and flat; Liver and kidney meridian; It has the effects of calming the liver and suppressing yang, improving hearing and eyesight, calming the nerves and relieving asthma. Indications: hyperactivity of liver yang, dizziness, palpitation and insomnia, tinnitus and deafness, asthma due to kidney deficiency.
Application in traditional industries
When talking about magnetic sources, electromagnetic induction and magnetic devices of magnetic materials, we have mentioned some practical applications of magnetic materials. In fact, magnetic materials have been widely used in all aspects of traditional industry.
For example, electrification is impossible without magnetic materials, because power generation requires generators, power transmission requires transformers, motors require motors, and telephones, radios and televisions require speakers. Magnetic steel coil structure is used in many instruments.

12, magnetized water can prevent boiler scaling.
13, magnetized seeds can increase crops to some extent.
14, magnetotherapy
15, rocks of different geological ages often have different magnetism. Therefore, we can judge the geological age change and crustal change according to the magnetism of rocks.
16, magnetic beneficiation
17, magnetic materials are also widely used in the military field. For example, ordinary mines or mines can only explode when they hit the target, so their functions are limited. If a magnetic sensor is installed on a mine or a mine, because the tank or warship is made of steel, when they approach (do not touch the target), the sensor can detect the change of the magnetic field, which makes the mine or mine explode and improves the lethality.
18. In modern wars, air superiority is one of the keys to winning the battle. However, the aircraft is easily found by enemy radar during flight, which is very dangerous. In order to avoid the surveillance of the enemy radar, a special magnetic material-absorbing material can be coated on the surface of the aircraft, which can absorb the electromagnetic waves emitted by the radar, so that the radar electromagnetic waves are rarely reflected, so that the enemy radar can not detect the radar echo, find the aircraft, and make the aircraft achieve the purpose of stealth. This is the famous "stealth plane". Stealth technology is a hot spot in the field of world military scientific research. The American F 1 17 stealth fighter is an example of the successful application of stealth technology.
19. In the "Star Wars" plan of the United States, a new weapon "electromagnetic weapons" was developed and studied. Traditional artillery uses the thrust generated by the instantaneous expansion of ammunition when it explodes to accelerate the projectile quickly and push it out of the bore. The electromagnetic gun puts the shell in the solenoid and energizes the solenoid, then the magnetic field generated by the solenoid will give a great impetus to the shell and shoot it out. This is the so-called electromagnetic gun. Similar to electromagnetic missiles.

Question 5: What role do magnets play in daily life? 1 The simplest thing is a compass.
A screwdriver with a magnet head can clamp the screw and is very convenient to use.
Magnetic whiteboard, commonly used in small class teaching.
4 speakers are inseparable from magnets.
5 motor
Question 6: What are the properties of magnets? What is the purpose of magnets? Characteristics of magnet:
Magnets are magnetic and can attract iron objects;
2. Magnets also have magnetic poles, which are divided into N poles and S poles.
The application fields of magnets are as follows:
1. Motor field: VCM, CD, DVD-ROM, wind generator, motor, servo motor, micromotor, motor, vibration motor, etc.
2. Mechanical equipment: magnetic separation, magnetic separator, magnetic crane, magnetic machinery, etc.
3. Medical care: nuclear magnetic vibrators, medical instruments, magnetotherapy health products, magnetized oil economizer, etc. 4. Electro-acoustic field: speakers, receivers, microphones, various stereos, etc.
5. Electronic appliances: vacuum circuit breakers with permanent magnet mechanism, magnetic latching relay, sensors, etc.
6. Other industries: magnetized wax remover, pipeline descaler, magnetic fixture, automatic mahjong machine, magnetic lock, door and window magnets, luggage magnets, leather magnets, toy magnets, tool magnets, and craft gifts.
I hope my answer can help you!
Question 7: What is the use of magnets? There are two things that can be called magnets, which are roughly called magnets and electromagnets.
One is natural or artificial, which is always attractive to iron, and the other is to make the iron core magnetic by artificially energizing its periphery.
Magnetite is always magnetic and can be used to induce other magnetic fields, such as a compass. The advantage of this kind of thing is that it is always effective and does not consume anything.
Electromagnets are magnetic only when they are energized. Although there is electricity consumption, we can control when they are magnetic, such as using electromagnets as weight lifters. At the same time, power consumption can also be used as a measurement signal, for example, for mine clearance. . .
Question 8: What items are equipped with magnets in daily life? What's the role? 1: Needless to say, headphones are used in speakers, made of NdFeB or ferrite magnetic materials.
2: TV is the same as above, used on speakers; Made of NdFeB or ferrite magnetic material.
3. Refrigerator door, made of extruded rubber magnet.
4. It is close to the door of the disinfection cabinet, and there is an extruded rubber magnet inside.
5: The interface of mobile phone shell adopts NdFeB strong magnetism and iron shell.
1. compass
2. Behind the loudspeaker
3. Magnetic door suction
4. Buckles of bags and boxes
When you want to find some small iron objects on the ground, you can use magnets to attract them.
