Physics Electromagnetism The Electric Field

	The Electric Field Lines:
	By convention, the lines of the electric field move away from a positively charged particle and move towards a negatively charged particle. When a positively charged particle like proton is near a negatively charged particle like an electron, then the electrical field goes from one to the other as follows: The electric field lines are not continuous and they always start from positive charge and meet at negative charge. Following are the points to be remembered while drawing the electric field lines: 1- The lines must begin on a positive charge and terminate on a negative charge. 2- The number of lines drawn leaving a positive charge or approaching a negative charge is proportional to the magnitude of the charge. 3- No two field lines can cross.
