Intro to Magnetism, Magnetic Fields, Dipoles, Permeability - Physics

This video explains the meaning and definition of magnetism in simple terms using examples (e.g. the earth, compass), what do magnets attract, magnetic field, flux and pole, difference between electric and magnetic field, what is meant by magnetic dipole, what causes it and how a magnet works. The magnetic permeability constant is also covered, including units, formula, definition and value for materials like aluminium (paramagnetic) and which material has high magnetic permeability (ferromagnetic). All materials have the diamagnetism property.
