Research on the Equation of the Magnetic Field Caused by Magnets

Published: 10 September 2022 Publication History

Abstract

In this paper, the variational form is used to analyze the existence and uniqueness of the corresponding partial differential equations. In addition, the equation of the magnetic field induced by the magnet is also investigated. By constructing the corresponding Hilbert space and variational formulation, we can deduce that the equation admits a unique solution under some assumptions.
