A portal moves northwards pushed by Earth's magnetic field and falls under gravity. Manipulating gravity is not readily accessible, but a fan coil that generates a spinning magnetic field is.
This experiment should be done small. The exit portal is only a few millimeters away.
When the portal is opened wide enough,
you will have one small spinning portal, when the entrance and exit (beginning and end) are just millimeter apart.
What happens when you are able to spin time, a tiny rod of time energy?
Good luck.
