These versatile high-performance ring magnets, with north and south poles on opposing circular faces, have many uses. They are used in many everyday appliances such as vacuum cleaners plus motors, مولدات كهرباء, rotor shafts and more. They can even be used to demonstrate intriguing ‘eddy currents’ using a 15mm copper pipe. Simply slide the ring over the pipe and let it slide down its length and watch it slowly descend as the eddy currents produced create a dampening effect. Compare this with our unmagnetised rings of the same dimensions by repeating and watch as the unmagnetised ring slides down the pipe in an instant. A great way to bring magnets to life in the classroom.
The 20mmx10mmx10mm ring magnet is a big and strong ring magnet. ويمكن ربطه بحبل واستخدامها لسحب البحيرات والجداول لأجسام معدنية. كما يمكن انسحب على الحائط أو السقف لعقد أدوات أو أشياء أخرى. تعدد الاستخدامات.
