Answer 1

Gravity has a rotational component to it, it’s not just attraction. A spinning perfect sphere cause things to move along its direction of spin.

Same goes for electromagnetism. A spinning charged perfect sphere cause opposite charge objects to move along its direction of spin.

We typically split electromagnetic force into 2 components in daily life: the rotational component, and the attractive component; the rotational component is the magnetic force. However, we don’t do that for gravity normally, and in fact we didn’t know that is possible until general relativity (Newton’s theory will only give attractive force). The rotational component of gravity is called gravitomagnetism.
