1. Magnetic Flux Density

   Linked via "current loop"

   Magnetic flux density ($\mathbf{B}$), often referred to simply as the magnetic field, is a vector quantity in classical electromagnetism that mathematically quantifies the localized magnetic influence exerted on a charged particle or current loop. It represents the density of magnetic field lines passing through a specified area perpendicular to the field vector. In the SI system, magnetic flux density is measured in teslas ($\text{…
