Demystifying Electromagnetics, Part 3 – Magnets

Why do magnets attract or repel and what’s that got to do with conducting loops of wire? Peter and Petronella Proton help explain.

Electric Fields without and with a conductor

Demystifying Electromagnetics, Part 2 – Wires

Ohm’s Law is just a flow rate, analogous to fluid mass flow. What’s that got to do with EM and what is Temperature and Joule heating anyway?

Demystifying Electromagnetics, Part 1 – Fields and Analogies

This blog series will strive to demystify (low frequency) EM by way of pictures and analogies, with as few equations as possible, by introducing a series of applications of increasing complexity. In this first blog we’ll and start to look into the electric field with the use of some analogies.

Trace, plane and thermal via heat spreading

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.


Flow Visualization and the Beauty of the Vortex Dome

Fluids tend to be transparent, which is problematic for flow visualization. Rheoscopic fluids get round this by seeding the flow with reflective particles.

Chaotic Fluid Dynamics Part 4 – Finding Feigenbaum

A 29 year old ambition finally achieved with the help of Simcenter FLOEFD for NX!

Chaotic Fluid Dynamics Part 3 – Wheels

Rayleigh–Bénard convection involves the transport of heat from a hot bottom surface to a cold top surface. If the temperature…

Chaotic Fluid Dynamics Part 2 – Butterflies

For want of a nail the shoe was lost.
For want of a shoe the horse was lost.
For want of a horse the rider was lost.
For want of a rider the message was lost.
For want of a message the battle was lost.
For want of a battle the kingdom was lost.
And all for the want of a horseshoe nail.

Chaotic Fluid Dynamics Part 1 – Rabbits

A person walks into a bar and asks the bartender “what’s the difference between period doubling routes to turbulence and fluffle demography?” The bartender replies “less than you might think”.
