Then put the copper ring on the paper clip holder like this, the copper wire ring will rotate under the action of the magnetic force~

Conductive Slip Ring

Conductive slip rings are one of the most popular types of electrical connectors. They consist of an insulating sleeve enclosing two metal contacts, with a small gap between them. When current is applied to the ring, it creates resistance between the contacts, which can be used to form a continuous circuit. They can be used in a wide range of applications, such as medical equipment, robotics, aerospace systems, and more. The construction of a conductive slip ring typically consists of two rotors (or rings), with each one containing a number of stationary contacts. When the rings rotate, the contacts move past each other and create an electrical connection.


In today's increasingly electronic world, the need for efficient and reliable power transmission is more important than ever. That's why more and more businesses are turning to slip rings as a means of transmitting power in a variety of applications. Slip rings are electrical connectors that allow current to flow continuously through a rotating assembly, making them ideal for use in devices that require uninterrupted power transmission, such as motors, generators, and wind turbines.
