The compass has served as a navigational aid to many tourists‚ travelers‚ and numerous explorers. Though the compass has served well in navigation‚ it has affected and improved mankind greatly. In China‚ building was refined in many ways by the compass. It has enabled many to find positions‚ direction or route. No one knows when‚ where‚ or by whom the compass was invented (dEstaing and Young 153). We do know though‚ that there were numerous inventors of the compass. The first compass was invented

The magnetic separator is one of commonly used preparation equipments in magnetic separation factory. It has dry and wet two types. According to types of magnets‚ it can be divided into permanent magnet type and electromagnet type. It is also can be divided into strong magnet type‚ middle magnet type and weak magnet type according to the magnetic field strength. Different magnetic separators have different characteristics and performance. 1‚ to maintain good lubrication condition is to extend the

Electromagnets! An electromagnet is a type of magnet in which the magnetic field is produced by the flow of electric current. The magnetic field disappears when the current is turned off. Electromagnets are widely used as components of other electrical devices‚ such as motors‚ generators‚ relays‚ loudspeakers‚ hard disks‚ MRI machines‚ scientific instruments‚ and magnetic separation equipment‚ as well as being employed as industrial lifting electromagnets for picking up and moving heavy iron objects
