Abstract
The utility model provides a power generating anchor demonstrating instrument in order to solve a problem that teaching demonstration effect is affected enormously due to lack of a good demonstrating instrument used for electromagnetic induction power generation demonstration at present in a middle and primary school prior physics teaching process. The power generating anchor demonstrating instrument includes a pedestal and a support frame arranged on the pedestal. The support frame is provided with a swing arm that can swing. A free end of the swing arm is provided with a permanent body. An induction coil is arranged on a swing path of the permanent magnet. Two ends of the induction coil are connected with an indicating device. According to the utility model, power generation is realized through the cutting of the induction coil of the swinging permanent magnet, so that the demonstration of electromagnetic induction power generation is realized. Therefore, the power generating anchor demonstrating instrument is simple in structure and distinct in demonstration effect, thereby facilitating the proceeding of physics teaching demonstration substantially.
