Abstract. A magnetometer is an instrument to measure the magnitude and direction of a magnetic field. The most commonly used magnetometric technique to characterize magnetic materials is vibrating sample magnetometry (VSM). VSMs can measure the magnetic properties of magnetically soft (low coercivity) and hard (high …

Inclined Screen. Inclined screens are the most basic type of screen, fixed to an inclined frame at an angle of between 15° and 30°. The entire body of the screen vibrates on helical springs circularly with the same characteristics and material flow is supplied by gravitational acceleration. The slope of the inclined screen is fixed, although ...
