Scientists create device invisible to magnetic fields

Scientists have developed a device that can hide objects from static magnetic fields. The device is a cylinder made from high-temperature superconducting materials, coated with layers of iron, nickel, and chrome. These layers work together to repel and attract magnetic fields, effectively cloaking the cylinder. This technology could have practical applications, such as concealing a pacemaker during an MRI scan or making submarines undetectable.
