**Inquiry question: Under what circumstances is a force produced on a current-carrying conductor in a magnetic field?**

**Students:**

β investigate qualitatively and quantitatively the interaction between a current-carrying conductor and a uniform magnetic field πΉ = ππΌβ₯π΅ = ππΌπ΅sinπ to establish: (ACSPH080, ACSPH081)

β conditions under which the maximum force is produced

β the relationship between the directions of the force, magnetic field strength and current

β conditions under which no force is produced on the conductor

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

β analyse the interaction between two parallel current-carrying wires and determine the relationship between the International System of Units (SI) definition of an ampere and Newtonβs Third Law of Motion (ACSPH081, ACSPH106)
