Pole machines, packet machines) (below ф80) with unintentional grinding (unintentional grinding machine) cylinder greater than 80mm must be used to complete the grinding of blocks with a holes equipment. And if the magnetic sensor is installed on the mines or mines, because the tanks or warships are made of steel, when they are close (without contact with the target), the sensor can detect the change of the magnetic field to explode the mines or mines and increase the lethality.

In order to avoid the monitoring of enemy radar, you can apply a special layer of magnetic material -suction material on the surface of the aircraft. The US F117 stealth fighter is an example of successful use of stealth technology. Because all substances have a strong or weak magnetism, if they gather together to form a mine, then they will inevitably interfere with the geomagnetic field in the nearby area, causing Strong Motor Magnet factory abnormalities in the geomagnetic field. Therefore, you can judge the changes in the geological age and the changes in the crust according to the magnetic assistance of the rock.

This is the famous "invisible aircraft". Different geological rocks often have different magnetic properties. Utilizing this feature, people have developed a magnetic selection machine to use the different magnetic and strong magnetic and weakness of the minerals with different ingredients to attract these substances with magnets, then the attractiveness they suffer Different magnetic minerals are separated to achieve magnetic minerals.

"Magnetic application in the military field": Magnetic materials have also been widely used in the military field. However, the aircraft was easily detected by the enemy's radar during the flight, which was greater dangerous.ufeffThe sun sunspot is a very intense area of the sun's magnetic field activity.
