Explaining Black Hole Jets and the Sun's Sunspots

I was curious about black holes and the jets and searched for information. This is my version of how black holes creates jets and it is the same mechanism that produces sunspots on the Sun. The jets are powered by the rotation and that energizes the magnetic forces of the black hole and of the Sun. I provide simple calculations for these forces. It is not based on theories but standard physics available in high school and college books.
