Tocodynamograph

Tocodynamics is the science of electric and magnetic alternating fields and electromagnetic transient processes in a linear or nonlinear electrical circuit.

The word “tocodynamography” is formed from the following words: “current” (a short word, including in the form I) - current, dynamography - methods of graphically depicting current in a graphical way, on paper. If current is electrical energy in the form of a charge, then changes in the electromagnetic field of the current are dynamic processes, and the field of research is a science called tocodynamics. This is a section of general electrodynamics that studies how the genesis of electric fields occurs and how magnetic fields change.

Basic laws of tocodynamics

Field of a constant source A constant field is static if, in the absence of charges, magnetic lines appear that are directed perpendicular to the plane limited by the contour of the EMF source. The flux of magnetic induction is not a vector quantity. It is a vector quantity and its magnitude is equal to the magnetic intensity flux *dA. and is equal to the change in the line of the magnetic needle, for example, over the time interval Δt F =∆NI┼dl=ΔS. The field current is constant in magnitude and varies in direction in Δ
