# Year 11 Physics

## Module 4 | Electricity and magnetism

### Content 3: Magnetism

#### Lesson 1 | Ferromagnetic materials

• investigate and describe qualitatively the force produced between magnetised and magnetic materials in the context of ferromagnetic materials (ACSPH079)

• investigate and explain the process by which ferromagnetic materials become magnetised (ACSPH083)

#### Lesson 2 | Fields around magnets

• use magnetic field lines to model qualitatively the direction and strength of magnetic fields produced by magnets, current-carrying wires and solenoids and relate these fields to their effect on magnetic materials that are placed within them (ACSPH083)

#### Lesson 3 | Magnetic fields around current carrying wires and solenoids

• use magnetic field lines to model qualitatively the direction and strength of magnetic fields produced by magnets, current-carrying wires and solenoids and relate these fields to their effect on magnetic materials that are placed within them (ACSPH083)

#### Lesson 4 | Investigating magnetic fields around a straight conductor

• conduct investigations into and describe quantitatively the magnetic fields produced by wires and solenoids, including:

– apply models to represent qualitatively and describe quantitatively the features of magnetic fields

#### Lesson 5 | Investigating magnetic fields around solenoids

• use magnetic field lines to model qualitatively the direction and strength of magnetic fields produced by magnets, current-carrying wires and solenoids and relate these fields to their effect on magnetic materials that are placed within them (ACSPH083)

• conduct investigations into and describe quantitatively the magnetic fields produced by wires and solenoids, including: (ACSPH106, ACSPH107)

– $B = \frac{\mu _{0}I}{2 \pi r}$

– $B = \frac{\mu _{0}NI}{L}$
