Faraday's law of induction

Also known as Maxwell–Faraday equation,

 . where:

 = Curl Operator

E = Electric Field (N/C)

B = Magnetic B-Field (T)

t = Time (s)

Gauss's Law

     

, where:

 = Electric Flux Through Surface S (V*m)

E = Electric Field (N/C)

Q = Total Charge within Surface S (C)

Gauss's Law for Magnetism

 , or

 , where:

 = Divergence

B = Magnetic B-Field (T)

S = Closed 3-D Surface

Lorentz Force

The force on a moving point charge due to an electromagnetic field:

, where:

F = Force (N)

q = Charge of Particle (C)

E = Electric Field (N/C)

v = Velocity (m/s)

 = Cross Product

B = Magnetic B-Field (T)

Planck-Einstein Equation

Also known as Planck's Relation, the energy of a photon is given by:

 , where:

E = Energy (J)

h = Planck's Constant (J*s)

f = Frequency (Hz)
