There are some tricky experiments in this topic, and it is well worth practising them in advance.
Magnetic fields will have to be shown; iron filings are a standard way to do this, but you may also find a magnaprobe useful –...
Demonstration: a shuttling ping-pong ball serves as a model of ions moving in an electric field.
Demonstration: comparisons with magnetic fields may be helpful here.
This episode introduces fields, field lines and equipotentials in the context of electric fields. Much of this is revision...
This episode introduces the above three quantities for the electric field. The students’ familiarity with the equivalent...
So far we have mainly concentrated on the non-uniform fields around point or spherical charges. We will now discuss the...
This shows the shape of electric fields, in much the same way that magnetic fields are demonstrated with iron filings.
An electric field exists in any region where a charged particle is subject to a force that depends only on the particle’s...
We all use electrical devices in our lives, but many misconceptions exist about how these circuits actually work. In these...
Recognising and celebrating outstanding contributions to the field of physics education.
