We assume the existence of magnetic charge, related to the magnetic field \( \mathbf{B} \) by the local relation:
\( \nabla \cdot \mathbf{B} = \mu_0 p_m \)
In the absence of magnetic charge, the curl of the electric field \( \mathbf{E} \) is given by Faraday's law:
\( \nabla \times \mathbf{E} = -\frac{\partial \mathbf{B}}{\partial t} \), which of the following is correct ?
1
This law is compatible with a time-dependent magnetic charge density
2
This law is incompatible with a time-dependent magnetic charge density
3
This law is an exception.
4
None of the above.
