Formulas of electricity and magnetism. The study of the fundamentals of electrodynamics traditionally begins with an electric field in a vacuum. To calculate the interaction force between two exact charges and calculate the electric field strength created by a point charge, one must be able to apply the Coulomb's law. To calculate the field strengths created by extended charges (charged filament, plane, etc.), the Gauss theorem is used. For an electrical charge system, the principle must be applied

When studying the topic "Direct Current" it is necessary to consider the Ohm and Joule-Lenz laws in all forms. When studying "Magnetism" it is necessary to keep in mind that the magnetic field is generated by moving charges and acts on moving charges. Here you should pay attention to the law of Bio-Savar-Laplace. Particular attention should be paid to the Lorentz force and consider the motion of a charged particle in a magnetic field.
