Price's Theorem

 

|Br| vs. t/M

The absolute value of the radial magnetic field at r = 20M as a function of time. For this simulation, the outer boundary was placed at 2000M, the numerical grid consisted of 6000 radial gridpoints, and the Courant factor was 0.5. The dashed line is a power law t-4, which approximates the late-time fall-off extremely well.


Asymptotic Decay : Price's Theorem

Same as above, except for the absolute value of the theta component of the magnetic field and the absolute value of the φ component of the electric field.
