Current is a flow of electrical charge carriers‚ usually electrons or electron-deficient atoms. The common symbol for current is the uppercase letter I. The standard unit is the ampere‚ symbolized by A. One ampere of current represents one coulomb of electrical charge (6.24 x 1018 charge carriers) moving past a specific point in one second. Physicists consider current to flow from relatively positive points to relatively negative points; this is called conventional current or Franklin current. Electrons

dry type magnetic separator is commonly used iron ore and manganese ore beneficiation equipment. It is the mainstream strong magnet separator‚ which is specialized in processing dry magnetic minerals. The wet type magnetic separator use liquid diluents to improve separation efficiency. The dry type magnetic separator requires that the material must be dry‚ and can move freely between the particles. Or it will affect the separation result‚ and even cannot separate materials.

following years‚ but it was not until the 1970’s that Japan and Germany showed interest in it and began researching and designing. The motion of the Maglev train is based purely on magnetism and magnetic fields. This magnetic field is produced by using high-powered electromagnets. By using magnetic fields‚ the Maglev train can be levitated above its track‚ or guide way‚ and propelled forward. Wheels and moving parts are eliminated on the Maglev train‚ allowing the Maglev train to essentially move
