Suppose the divergence of the magnetic field &vec;B is non-zero and is given as &vec;∇ · &vec;B = μ 0 ρ m , where μ 0 is the permeability of vacuum and ρ m is the magnetic charge density. If the corresponding magnetic current density is &vec;J m , then the curl &vec;∇ × &vec;E of the electric field &vec;E is:
- 1&vec;J m − ∂&vec;B ∂t
- 2μ 0 &vec;J m − ∂&vec;B ∂t
- 3−&vec;J m − ∂&vec;B ∂t
- 4−μ 0 &vec;J m − ∂&vec;B ∂t✓
Correct answer
−μ 0 &vec;J m − ∂&vec;B ∂t
