Charged Particles, Conductors and Electric and Magnetic Fields

Electromagnetism >

Inquiry question: What happens to stationary and moving charged particles when they interact with an electric or magnetic field?

Students:
● investigate and quantitatively derive and analyse the interaction between charged particles and uniform electric fields, including: (ACSPH083)
– electric field between parallel charged plates
– acceleration of charged particles by the electric field
– work done on the charge 𝑊 = 𝑞𝑉, 𝑊 = 𝑞𝐸𝑑,
● model qualitatively and quantitatively the trajectories of charged particles in electric fields and compare them with the trajectories of projectiles in a gravitational field
● analyse the interaction between charged particles and uniform magnetic fields, including: (ACSPH083)
– acceleration, perpendicular to the field, of charged particles
– the force on the charge 𝐹 = 𝑞𝑣⊥𝐵 = 𝑞𝑣𝐵sin𝜃
● compare the interaction of charged particles moving in magnetic fields to:
– the interaction of charged particles with electric fields
– other examples of uniform circular motion (ACSPH108)
