技術說明

一種電磁感應教具組，其包括滑車教具，其設有基台，於基台之前側設有軌道座、滑車及馬達，於馬達軸心結合金屬盤，軌道座水平地固設於基台之前側，滑車是以可水平滑動的方式結合於軌道座上並能夠朝向金屬盤進退移動，於滑車接近金屬盤之一端設有磁鐵單元，當馬達驅動金屬盤持續旋轉時，將滑車朝金屬盤移動或遠離，使磁鐵單元能夠與金屬盤產生電磁感應，藉由觀察金屬盤與磁鐵單元之間的效應強弱，使本發明能夠達到有效地教學電磁感應的效果。本發明的磁阻力教具可讓學生觀察磁鐵件於金屬管與非金屬管間的運動。本發明的電磁炮教具可讓學生了解金屬環有無裂縫對產生電磁感應的影響，了解法拉第定律及冷次定律。 Electromagnetic induction teaching aid kit has a trolley teaching aid having a base. A guiderail, a trolley and a motor are mounted on a front side of the base. A metal wheel is connected with a shaft of the motor. The guiderail is horizontally and securely mounted on the front side of the base. The pulley is horizontally connected with the guiderail and can be moved forward and backward to the metal wheel. A magnet unit is mounted on an end of the trolley and is adjacent to the metal wheel. When the motor drives the metal wheel to continuously rotate, the trolley is moved forward or backward to the metal wheel such that the magnet unit can induce the metal wheel to generate electromagnetic induction. By observation of the intensity of the induction, the present invention allows teachers to effectively teach electromagnetic induction. A magnet reluctance teaching aid of the invention allows students to observe how fast a magnet piece falls in a metal tube or a nonmetal tube.
