From the Wikimedia Commons description:

(a) The field of a magnetic source (right) is appearing as an isolated magnetic monopole when passing through the magnetostatic wormhole; the whole spherical device is magnetically undetectable. (b) The wormhole is composed of (from left to right) an outer spherical ferromagnetic metasurface, a spherical superconducting layer, and an inner spirally wound ferromagnetic sheet.

In other words, this is a diagram of how these scientists actually created a for-real wormhole in their lab. There’s more on their experiment here, in Nature.
