Demystifying Electromagnetics, Part 9 – Skin Effect

A conductor carrying an AC current will tend to have the current bunched up at its periphery. Why and why is this a problem?

Demystifying Electromagnetics, Part 8 – Losses

All the energy we utilise day to day originates from the sun. The fusion processes in our local star result…

Demystifying Electromagnetics, Part 7 – Solenoids

“I have no special talents. I am only passionately curious.” – Albert Einstein, March 11, 1952. Inspired by the great man himself, I was curious if the nail solenoid was powerful enough to pierce, say, a grape (it was a slow day).

Demystifying Electromagnetics, Part 6 – Relays

Over the last 5 blogs in this series we’ve introduced a set of EM building blocks, fundamental behaviours that hopefully have been demystified by the use of analogy. At last, and not before time, we can get on to an actual application – Relays.

Demystifying Electromagnetics, Part 5 – Ferromagnetic Cores

A coil of wire creates a magnetic field when a current passes through it. The magnetic field is strongest in…

Demystifying Electromagnetics, Part 4 – Inductors

Welcome to Part 4 in this blog series that hopes to demystify electromagnetics for those of you who might have a background in mechanical engineering, fluid flow and heat transfer. Ultimately we’ll be getting onto electric motors, generators, induction cooking, levitation, loud speakers etc. etc. but for now some more basics – Inductors.

Happy Geek Pride Day, but what does the ‘B’ stand for?

Can Simcenter Flotherm model Simcenter Flotherm modelling Simcenter Flotherm modelling the Mandelbrot set? Yes, but only on Geek Day.

Thermal Influence on Maximum Current Carrying Capacity

Superconductors aside, anything that conducts electricity will dissipate heat. The more current that flows, the more heat is dissipated, the hotter things will get. At some point a thermal limit is reached that imposes a maximum current carrying capacity constraint.
