Cern Keyring Super Conductor

The metal inside is a Niob-Titan mixture, capable of 17000(!) amperes in a nominal magnetic field of 8.3 teslas at the ATLAS detector at the LHC accelerator in CERN. If there is no magnetic field, it can hold 50000(!) amperes, given a temperature of 1.7 kelvin.

Each round "silver" conductor you can see in the image below consists of 6500(!) 6(!) micrometer(!) strands which is embedded in copper.
