Charge density formula class 12

WebCharge Density Formula. The charge density is the measure of electric charge per unit area of a surface, or per unit volume of a body or field. The charge density tells us how much charge is stored in a particular field. Charge density can be determined in terms of … 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.
