Physics 212: An Introduction to Electricity and Magnetism Professor David Weiss (lectures) Dr. Stephen Van Hook (administration) Spring 2008 For next time, read HRW 21.1-21.6 Four Fundamental Forces The motion of heavenly bodies Falling objects Radioactivity Neutrino physics The binding of quarks and nuclei Everything else! Electromagnetism Maxwell’s Equations : Four fundamental and inter-related “laws” about electricity and magnetism It is the underlying force behind most observable phenomena Electricity: lightning, electric current, electronics, your nervous system, … Magnetism: electric motors, MRI, … Radiation: light, x-rays, radio-waves, … Chemistry (and biochemistry): chemical bonds, reactions, … Solids… Specifically What You’ll Learn in Phys 212 Electric charges create electric fields Electric fields lead to forces on electric charges Moving electric charges (a.k.a. current ) create magnetic fields Magnetic fields lead to forces on moving electric charges Electric and magnetic fields store energy Changing electric fields create magnetic fields magnetic fields create electric fields } Light More generally, you will continue to learn how to reason physically.
