LHS46: Maxwell's four laws + 2 force equations

Force equation for Lorentz force left hand thumb rule 

is the force on a current carrying loop of fire in a magnetic field force is equal to NAB Omega sine Omega T where

Force equation considering reluctance force for a permanent magnet

F = B2A_sp/mu_0

Maxwell's first law

Gauss magnetic field law 

The net magnetic field over a closed surface, will be 0 because the magnetic poles exist only as a dipole

Maxwell's second law 

This law is called the Gauss electric field law

the net electric field over a closed surface need not be zero because electric monopoles exist. It will be a function of included electric charges inside the closed surface

Maxwell's 3rd law 

Faradays generator law

V = NAB omega sin omega T

Maxwell's 4th law 

this law is also called ampere circuit law 

it relates the Magnetic field intensity H around a conductor to the current flowing in the conductor and radius at which H is measured.
