Topic 2.1 Electric fields
Electric fields are described by the forced 'felt' by a charge
Coulomb's law is used to determine the force between charges
Vector addition is used to calculate the net force/field from multiple charges
Field structures and relative forces are shown graphically and calculated
Fields around and inside various shaped objects including smooth curves and sharp edges and poinst are considered.
Topic 2.2 Motion of charged particles in electric fields
The concept of work
The concept of voltage and electrical potential in relation to work
The motion of charges in electrical fields
Changes in Ek due to an electric field acting on a charged particle.
Topic 2.3 Magnetic fields
All moving charges create magnetic fields, in fact all changing electrical fields create a changing magnetic field at
right angles to them
Magnetic field strength is measured in tesla (T) and can be calculated
Topic 2.4 Motion of charged particles in magnetic fields
Magnets, magnetic materials, moving charges, and current-carrying conductors experience a
force in a magnetic field
Combining the effects of electric and magnetic fields on charged particles a range of calculations
can be performed related to cyclotrons including the path, velocity and energy of particles.
Topic 2.5 Electromagnetic induction
Electromagnetic induction is the process in which a changing magnetic flux induces a potential
difference in a conductor
Faraday's and Lenz' laws can be used to calculate various properties.
Topic assessment
Two pieces of assessment are introduced during this topic
- A SAT (skills and applications test) on the topic of electricity and magnetism
- A Completion Practical on electromagnetic induction
