Abstract
The formula for the emf Faraday induction from a domain wall moving in a microwire is derived. The time derivative of the magnetic flux in the measuring coil is expressed through a five-fold integral over the wall volume and over the coil section surface. The resulting expression is compared with those obtained previously with a simplified description of the measurement objects.
