### Content 2: The motor effect

#### Lesson 1 | The motor effect

• investigate qualitatively and quantitatively the interaction between a current-carrying conductor and a uniform magnetic field ($\vec{F} = \vec{B}I\vec{l}\sin \theta$) to establish: (ACSPH080, ACSPH081)
– conditions under which the maximum force is produced
– the relationship between the directions of the force, magnetic field strength and current
– conditions under which no force is produced on the conductor

#### Lesson 2 | Force between parallel conducters

• conduct a quantitative investigation to demonstrate the interaction between two parallel current-carrying wires

• analyse the interaction between two parallel current-carrying wires ($\frac{\vec{F}}{l} = \frac{\mu _{0}}{2\pi } \times \frac{I_{1}I_{2}}{\vec{r}}$) and determine the relationship between the International System of Units (SI) definition of an ampere and Newton’s Third Law of Motion (ACSPH081, ACSPH106)
