University of Leicester engineers have unveiled a concept for a device designed to magnetically “cloak” sensitive components, making them invisible to detection.

A magnetic cloak is a device that hides or shields an object from external magnetic fields by manipulating how these flow around an object so that they behave as if the object isn’t there.

In Science Advances, the team of engineers demonstrate for the first time that practical cloaks can be engineered using superconductors and soft ferromagnets in forms that can be manufactured.
