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. |
