What You’ll Learn in Phys 202
n Four Fundamental Laws aboutelectromagnetism:
MAXWELL’s EQUATIONSn Basis for many phenomena in Nature:
ä Electricity: lightning, electric current,electronics, your nervous system...
ä Radiation: light, x-rays, radio-waves,...ä Magnetism: electric motors, MRI,...ä Chemistry: chemical bonds, reactions,...
What You’ll Learn in Phys 202
n Electric Charge è Electric Field èForce on other electric charges
n MOVING electric charge (current) èMAGNETIC field è Force on otherMOVING electric charges
n Time-varying current è Electric Fieldn Electric and magnetic fields store
energy
Electric Charge
•Two types of charges: positive/negative•Like charges Repel•Opposite charges attract• Atomic structure :
• negative electron cloud• nucleus of positive protons, uncharged neutrons
Conductors
Mobile “Sea” of Electrons
Static Positive Ions
Insulators
Static Positive Ions
Electron Cloud:“immobile” but can be distorted
