Are we teaching electricity the wrong way around?

It’s the beginning of another school year, and another crop of year 9/10 students is about to not get the hang of what electricity is all about, writes Bernie Hobbs.

The right way: “Maxwell-lite: fields, current and energy for beginners” The main points are:

  1. Separating positive and negative charges creates an electric field with stored energy.
  2. Whenever charges are moving in an organised way (like electrons in an AC or DC current), they create a magnetic field.
  3. If you’ve got an electric field and a magnetic field together you’ve got yourself an electromagnetic field — and energy will flow through that field.
