Strand 3: Electric & Magnetic fields
and their interactions

Simulations

3.1  Charge interactions

• Force between two charges
• Demonstrating a gold leaf electroscope
• Charging a single object by induction
• Van de Graaff generator
• Demonstrating a Faraday cage

3.2  Modelling electric fields

>     Electric fields in the lab

>    Charged particles in an electric field

3.3  Electric circuits

• To model resistors in series and in parallel in an electrical circuit.
• Resistors in parallel or in series
• Circuits in series and parallel
• Make your own circuit (PhET resource)
• IV graphs
• PN junction diode
• A transistor as a switch or amplifier
  
  

3.4 Magnetic fields are permanent and temporary magnets

• Magnets interacting
  
  

3.5 The force experienced by a current-carrying conductor in a magnetic field.
