Lesson Plan: The Torque on a Current-Carrying Rectangular Loop of Wire in a Magnetic Field Physics

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 𝜏=𝐵𝐼𝐴𝑁(𝜃)sin,
  • 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.
