Electric field strength of the force that would be observed in the presence of a test
charge
Electric field lines lines begin and end only at charges (+ to -) or infinity
lines are closer together where the field is stronger
larger charges have more lines
lines never cross
at any location the direction of the electric field is tangent to the electric
field line that passes through that location

Magnetic field measure of the force experienced by a moving charge with v according to
Lorentz force model F = qv μH, Lorentx force Law: F = q(E + v uH)
+ and - poles
direction of a magnetic field = direction of the force on a north pole (RH
rule)
3 branches of electromagnetics Electrostatics - stationary charges - Electric field intensity E (V/m) - electric
flux density D (C/m²) - D = εE
Magnetostatics - Steady currents - magnetic flux density B (T) - magnetic
field intensity H (A/m) - B = μH
Dynamics - time varying fields/currents - (E,D) coupled to (B,H)
μ = magnetic permeability (F/m)
ε = electric permeability (H/m)
σ = conductivity (S/m)
homogeneous medium constituent parameters are constant throughout
propagation constant / wave number k = 2π/λ
when k = vector it defines the em propagation direction
