摘要
超导楞次定律实验装置由磁块、3个金属环(铜、铝和不锈钢)和1个超导环以及导向管组成.除了传统楞次定律实验装置的展示内容,该装置还可以展示磁块在超导环上的悬浮现象,磁块在穿过金属环和超导环时的受力情况不同.
T he superconducting device for Lenz law experiment consisted of a magnetic block , three metal rings （copper ,aluminum and stainless steel） ,a superconducting ring and a guiding tube . In addition to the conventional experimental content ,this device could also demonstrate the levitation phenomenon of magnetic block over superconducting ring .The forces acting on the magnetic block were different when it passed through the metal rings from that when it passed through the supercon-ducting ring .
