The book ‘Uniform formula of interaction of fields and bodies’ studies the process of interaction (formula of interaction) of fields between themselves and interaction of fields with bodies situated in those fields. The uniform formula of force of interaction of fields and bodies is derived. Any field is a space filled with moving microparticles. The process of interaction of microparticles of fields with each other consists of the following. Directed flux of microparticles of a field creates tension on equipotentional surfaces. The tension is an ability of directionally moving particles to make action (pressure) Definition of pressure is introduced. The formula of interaction of microparticles of a field with a body or another field within this field is determined. The formula of interaction consists in the following:
