Ch 14: The Physics of Magnetism

Watch video lessons on the physics of magnetism and learn about magnetic fields and force, electromagnetic induction and more. These video lessons are short and engaging and make learning easy!

Physics of Magnetism - Chapter Summary and Learning Objectives

This chapter of Intro to Physics examines magnetic fields and electromagnetic induction. You'll find out about materials that can be magnetized and factors that affect the strength of magnetic fields. Lessons are included on the Biot-Savart Law and Faraday's Law of Electromagnetic Induction, and you'll find videos on transformers and conductor to conductor currents. At the end of this chapter, you'll be familiar with:

• Poles and dipoles
• Shape and direction of field lines
• Practical applications for magnetic forces
• Variables that affect induction

Video Objectives
Magnetic Force: Definition, Poles & Dipoles Describe the root of magnetism and properties of magnets.
What is a Magnetic Field? Learn to detect magnetic fields and determine the strength of the field. Describe ferromagnetic materials.
How Magnetic Fields Are Created Explain how magnetic fields are created by moving charges. Examine electromagnets and factors that affect the strength of the field.
How Magnetic Forces Affect Moving Charges Explain why relative motion is important and discuss direction and strength of the force.
