Eq. (15)

The radial component of the magnetic field is given by

[tex]B_r = g_{11} ε^{01μν} F_{μν}[/tex]

Where does this equation come from?

Similar to the electric charges, the Gauss's flux theorem for the magnetic field gives

[tex]const = P/√4π[/tex]

where P is the total magnetic charge of black hole.

Why does the magnetic charge exist here?
