Abstract
A flexible magnetic component can include a magnetizable powder including a rare earth element. The flexible magnetic component can also include a polymer binder. The flexible magnetic component can define a first surface and a second surface opposite the first surface. A first magnetic field adjacent to the first surface can have a field strength at least 3 times greater than a field strength of a second magnetic field adjacent to the second surface, and the flexible magnetic component can elongate greater than 20% before a permanent deformation occurs.
