Abstract: The aim of this paper is to facilitate a better understanding of four electrical phenomena: electromagnetic induction, transformer operation, wireless charging, and the skin effect. Central to this understanding is the principle that magnetic flux density is of primary importance for induction. John Ambrose Fleming established the Fleming’s Right-Hand Rule, which dictates the relationship between motion, fields, and current: the thumb represents the direction of motion (Force), the index finger represents the magnetic field (B) from North to South, and the middle finger represents the direction of the induced current (I). This paper proposes that F be used specifically to denote magnetic flux density within this framework.
