Understand the change in electric potential for a constant electric field and a point charge. This video explains the core concepts, key equations, and how electric potential varies with position in a ...

An electric charge (like a proton) creates an electric field in the region around it. This field points away from positive charges and decreases in strength as it gets farther away from the charge.

Researchers at Paul Scherrer Institute PSI have demonstrated an innovative method to control magnetism in materials using an energy-efficient electric field. The discovery focuses on materials known ...
