|The Electric Field||The Magnetic Field|
|Coulomb's Law:||Biot-Savart Law:|
|Gauss's Law:||For Magnetism:|
|Definition of Electric Potential:|
If a closed path is specified for the line integral,
so that point B is located at point A
(where the potential must have the same value!):
|Definition of Conservative Field:|
The electric field is conservative;
this allows a scalar potential to be defined.
It turns out that this integral is not zero!
Thus the magnetic field is not conservative
and no scalar magnetic potential may be defined.
