Investigation of the skin effect in alternating currents

#### Abstract

My research is on the investigation of the skin effect in alternating currents. My project is broken down into 4 sub-aims. The first aim would be, to be able to mathematically model the distribution of current in the radius of the wire, which consists of the applications of the Maxwell equation and solving zeroth order differential Bessel equations of the first kind. The next aim would be to computationally plot out the desired current readings as the depth of the wire increases from the surface, using the Matlab software. The third aim that I have would be conducting an experiment, which involves bundling it multiple silver wires together, and a section of it is where the wires would diverge and separate from each other before they converge into a bundle again. An alternating current is passed through them, before measuring the current distribution flowing through each wire. Lastly, it is to compare on which mathematical model is the most accurate in modelling the skin effect in the wire. This would be a contribution to physics, in the field of electromagnetism as this shows the interaction of the electromagnetic fields within a conductor, and it is also a contribution to the engineering field as engineers can better design conductors to minimise power losses.
