Has Boeing been exploring the printing of 3D printing of levitating objects? Yes, Boeing has patented technology to 3D print objects while levitating in space. PatentYogi has presented a video that explains what Boeing had ...
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.
