The best way to determine the direction of the magnetic field at point p, where the wire and magnet are located, according to the right hand thumb rule is for a long, straight line carrying current.
An electric charge, an electric current, and magnetic materials are all affected magnetically by a magnetic field, which is a vector field. A force perpendicular to the magnetic field and its own velocity acts on a moving charge in a magnetic field. Electron flow in an electric circuit is referred to as current. Because of potential differences, electrons move. The rate of change of charge over time, or current, is another name for it. In a circuit analysis, the current flow direction. about circuit analysis.
