3M™ Magnetic Shielding Materials are thin magnetic materials that interact and influence electromagnetic (EM) fields. These materials help protect sensitive electronic components and circuitry by shielding external low magnetic fields (<1MHz).

The high magnetic permeability and low magnetic loss help enable flux field redirection for applications less than 20MHz.
