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

**Students:**

● investigate qualitatively and quantitatively the interaction between a current-carrying conductor and a uniform magnetic field ? = ??⊥? = ???sin? 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

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

● 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 Newton’s Third Law of Motion (ACSPH081, ACSPH106)
