A magnetic field is the region
A magnetic field is the region around a magnet where magnetic force can be experienced. It is characterized by direction and strength, represented by
Current
Current-carrying wires produce circular magnetic field lines around them. The direction is determined by the right-hand thumb rule. For straight wires
A moving charge in a magnetic
A moving charge in a magnetic field experiences a force given by F = qvB sinθ. For current-carrying wires in magnetic fields, the force is F = ILB sin
