PHYS 1112 -
Introductory Physics II
Lesson 12 - Magnetism II
Study Assignment:
Study: Chapter 22, Sections 22.3 - 22.5, 22.7
Lesson notes:
In this lesson, we will examine the magnetic force on a charged particle moving in a magnetic field, and the magnetic force between parallel current-carrying wires. We will also introduce Ampere's law and use it to calculate magnetic fields produced by long straight conductors and solenoids.
Objectives:
1. Be able to apply the magnetic force relationship to calculate the force and describe the motion on a moving charged particle in a region of space where a magnetic field is present.
2. Be able to calculate the force on a current-carrying conductor in a magnetic field.
3. Be able to calculate the torque on a flat current loop in a magnetic field.
4. Be able to use the right hand rule to determine the direction of the magnetic field produced by a current in a conductor.
5. Be able to calculate the magnetic force between two parallel conductors and understand the definition of the ampere and coulomb in terms of this force.
6. Be able to calculate the magnetic field produced by currents in a long straight conductor and a solenoid.
Vocabulary:
current loop
permeability of free space
solenoid
