Lesson Plan: The Torque on a Current-Carrying Rectangular Loop of Wire in a Magnetic Field Physics • Third Year of Secondary School
This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to calculate the torque on a current-carrying rectangular loop of wire in a uniform magnetic field.
Objectives
Students will be able to
- calculate the magnetic torque on a current-carrying rectangular loop of wire in a magnetic field at an angle to the area of the loop using the formula ,
- define the magnetic dipole moment of a current-carrying rectangular loop of wire in a magnetic field as the ratio of the torque on the loop to the strength of the magnetic field.
Prerequisites
Students should already be familiar with
- magnetic flux,
- magnetic forces on straight current-carrying conductors.
Exclusions
Students will not cover
- electromagnetic induction,
- angular kinematics.
