Shape-morphing magnetic soft machines have diverse applications in minimally invasive medicine, wearable devices and soft robotics. However, most magnetic programming approaches are inherently coupled to the fabrication processes, ...
Magnetic fields surround magnetic materials and electric currents and are detected by the force they exert on other magnetic materials and moving electric charges. The magnetic field, at a given point, is specified by both a direction and a magnitude (or strength); as such it is a vector field.
In special relativity, the electric field and magnetic field are two interrelated aspects of a single object, called the electromagnetic field. A pure electric field in one reference frame is observed as a combination of both an electric field and a magnetic field in a moving reference frame.
