Description Brand Exploring KidName Wind Direction And Speed ExperimentMaterial Plastic hardware ABS environmental protection plasticFeatures Why can field magnets drive aluminum plates This principle is relatively deep and not easy to understand However it is basically the same as the principle that the aluminum circular plate in the home electric meter will rotate Mainly when the field magnet rotates Some whirlpool currents are generated in the aluminum plate These whirlpool currents are also accompanied by a magnetic effect The magnetism of the field magnet and the magnetism of the whirlpool current on the aluminum plate will also have the effect of attracting and repelling each other which causes the force of the aluminum plate to rotate Definition of Technology TermsAnemometer English name anemometer An instrument that can automatically and continuously record wind speed As the name suggests an anemometer is an instrument for measuring the air speed There are many types of it The wind cup anemometer is commonly used in meteorological stations It consists of three parabolic cones and empty cups fixed to the bracket in a 1200 each The concave surface of the empty cup is all facing one direction The whole sensing part is installed on a vertical rotating shaft and under the action of wind the wind cup rotates around the shaft at a speed proportional to the wind speed Another type of rotary anemometer is a propeller anemometer which is composed of a
