👉 In physics, "insphering" refers to a phenomenon where a charged particle is able to escape from an electric field without leaving the region of its original motion. This effect occurs when a charge experiences a magnetic force that opposes the direction of the electric field. For example, consider a proton moving through a uniform electric field with a magnetic field perpendicular to it. As the proton moves along the x-axis, it experiences a force from the electric field that is directed towards the origin (positive z-direction
