# Year 12 Physics

## Module 6 | Electromagnetism

### Content 1: Charged particles, conductors and electric and magnetic fields

#### Lesson 1 | Charges in electric fields

• investigate and quantitatively derive and analyse the interaction between charged particles and uniform electric fields, including: (ACSPH083)
– electric field between parallel charged plates ($\left | \vec{E} \right | = -\frac{V}{\vec{d}}$)
– acceleration of charged particles by the electric field ($\vec{F} = m\vec{a}$, $\vec{F} = q\vec{E}$)
– work done on the charge ($W = qV$, $W = qEd$, $K = \frac{1}{2}mv^{2}$)

• model qualitatively and quantitatively the trajectories of charged particles in electric fields and compare them with the trajectories of projectiles in a gravitational field

#### Lesson 2 | The motion of charged particles moving in a uniform magnetic 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 ($\vec{F} = q\vec{v}\vec{B}\sin \theta$)

• 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)
