Magnetic Permeability

Mr. Andersen explains magnetic permeability, the ability of materials to create internal magnetic fields. He begins by discussing magnetic fields using bar magnets and a compass. The concept of magnetic permeability is introduced, highlighting its measurement in free space and materials. The video explains how to measure permeability using a toroid and compares the permeability of different materials, emphasizing the high permeability of iron. The video concludes with a discussion on relative permeability, comparing materials like wood, aluminum, and magnetic elements.
