Scientists Design A Novel Magnetic Cloaking Device
"Scientists from the Universitat Autònoma de Barcelona designed a magnetic cloak that’ll both shield an object from an outside magnetic field and prevent an internal one from leaking out. It’s an antimagnet and it’ll have various military and medical applications. […] Take, for example, a person with a pacemaker who needs an MRI. The magnetic field of the MRI would damage the pacemaker and potentially harm the patient. Likewise, the pacemaker’s metal would interfere with the MRI’s magnetic field and throw off the machine’s results. A magnetic cloak could potentially negate these effects and let patients with a pacemaker receive a successful MRI scan."
