New devices, systems and methods are provided for protecting personnel and/or equipment from projectiles and other weapons. In some embodiments, a field of shielding particles or other interception media is activated on or about a location determined to intercept one or more projectile(s) or other physical threat(s). In some embodiments, electromagnets are included within such device(s) or system(s), for driving the interception media and/or projectiles away from the protected personnel and/or equipment. In some aspects of the invention, a control system using sensors with one or more sampling points are included, and determine the location and probable trajectory(ies) of an incoming projectile, and deploy the interception media to intercept the incoming projectile or other weapon.
