We have seen how a conducting wire moving with respect to an electric field ( B ) will experience forces upon its electrons. Consider the diagram below: Due to the proper ( perpendicular ) alignment of the loop and magnetic field, the maximum amount of DC current will be produced; however the voltages and currentsContinue reading “INTRODUCTION TO ELECTRONICS: DC Motors”

INTRODUCTION TO ELECTRONICS: DC Generator Fundamentals
In order to understand how DC generators produce electricity, it is crucial to understand how the relative motion of a conductor moving through a magnetic field ( B ) induces forces that put the conductor’s electrons into motion; however, prior to engaging in a discussion about electromagnetic induction, we must briefly re-examine how the magneticContinue reading “INTRODUCTION TO ELECTRONICS: DC Generator Fundamentals”
INTRODUCTION TO ELECTRONICS: Permeability and Reluctance of Magnetic Materials
Many uncanny comparisons can be made between the behavior of electric currents and magnetic flux ( ϕ ) within conductive materials. In the same way that some materials conduct current better than others, metallic materials differentially provide pathways through which magnetic flux can permeate. The permeability ( μ ) of any material is relative toContinue reading “INTRODUCTION TO ELECTRONICS: Permeability and Reluctance of Magnetic Materials”
INTRODUCTION TO ELECTRONICS: Magnetic Flux Density
Magnetic field lines represent regions of space that have the ability to enact forces upon charged particles in motion. Likewise, a stationary charged particle will experience a force from a nearby magnet when it is put into motion. Time and time again, we will see that the magnitude of the force enacted by a magneticContinue reading “INTRODUCTION TO ELECTRONICS: Magnetic Flux Density“
