Charged rotating sphere in five dimensions

I calculate the electromagnetic field of a charged rotating sphere in 4 + 1 dimensions. Griffiths calculates the magnetic field of a charged rotating sphere in 3 + 1 dimensions in example 5.11 in his book. In this post, I perform a similar calculation but in 4+1 dimensions.

The Weyl tensor of the D-dimensional Reissner–Nordström metric

In this post I write the Weyl tensor of the Reissner–Nordström black hole as a sum of squares of the electromagnetic field tensor.
