magnetism,electromagnetism and electromagnetic radiation

Gauss's Law

F = kpP / d squared

Faraday's Law

applies voltage to magnetic field and direction of electron flow

V = -dB / dt

Lorentzian force

total force of moving electrons

F = qE + qvB

dipoles

north pole

south pole

attract/repel

magnetic induction

magnetic permeability

ferromagnetic

easily magnetized

susceptibility >1

paramagnetic

very weakly magnetized

susceptibility 0-1

diagmagnetic

unaffected by magnet

repelled by magnet

susceptibility <1

no magnetism

randomly oriented

magnetism

aligned

imaginary lines of magnetic induction

B = F / p

solenoid

B = F / Idl

E = hf = hc / wavelength

electromagnetic radiation interacts with particle/wave

a resting electric charge radiates an electric field

a charge in motion geterates magnetic field

V = f times wavelength

photons speed up/slow down and have origin and termination

oscillating electric and magnetic fields cause wave's at 90 degrees

electromagnetic photons are determined by kinetic energy lost

conversion of energy into matter

E = mc squared

motionless electrons

electric field

magnetic field

Oersted's experiment

moving charged particle induces magnetic field perpedicular to its motion

interaction between electons's magnetic field is created by moving electons

F = qvB
