Description
- Spin this unique top on its base and watch it continue for hours, sometimes days without stopping
- Consists of a spinning top with a radically oriented magnetic field and an associated base that houses a conductive coil
- Its changing magnetic field induces a current in the coil which momentarily opens the switch to the battery resulting in powering up the electromagnet
- One 9 volt battery can last for over a week of continual use
- The spinning top is a great collection for people who love the movie Inception.
