Maximum magnetic field equation
WebA magnetic field is basically used to describe the distribution of magnetic force around a magnetic object. Magnetic fields are created or produced when the electric charge/current moves within the vicinity of the magnet. Here, the sub-atomic particle such as electrons with a negative charge moves around creating a magnetic field.
