    Em Orbit
In summary, the conversation discusses the possibility of magnet orbiting another magnet due to electromagnetic force, regardless of their mass. It also explores the concept of tidal effects on magnets and the potential for repulsive force between like-charged magnets to create orbital paths and tidal forces. The conversation also clarifies that magnets do not have "magnetic charges," but rather a north and south pole.

1. Can a magnet orbit another magnet (of opposite charge) despite the fact that their masses are insufficient to generate the orbit; i.e., their orbits are caused only by the EM force?

2. Would/could the EM attraction between them generate tidal effects on the two magnets?

3. If you had two magnets with like charges (such that there is a repulsive force between them), is there a possible speed&trajectory that one of them could assume relative the to other such that it would yield an orbital path? And if so, what about weird reversed tidal forces (flattening instead of elongating)?

The 1st 2 Qs ask whether you can have EM-attraction orbits & tides in the way that we already know we can have gravity-attraction orbits & tides. The 3rd Q asks whether we can have EM-repulsion orbits & tides?

Magnets always have a north and a south - there are no "magnetic charges".

Yes, Orbits of a magnet depend on EM force.
Orbits of a magnet does not depend on mass.
 

1. What is the difference between attraction and repulsion in EM orbits and tides?

Attraction and repulsion refer to the forces acting between two objects due to their electric charges. In EM orbits, attraction is the force that keeps an object in orbit around another object, while repulsion is the force that causes objects with the same charge to repel each other. In tides, attraction is the force that causes the ocean to be pulled towards the Moon, while repulsion is the force that causes the ocean on the opposite side of the Earth to be pushed away from the Moon.

2. How do EM orbits and tides demonstrate the principles of gravity?

EM orbits and tides demonstrate the principles of gravity through the force of attraction between objects with mass. In EM orbits, the gravitational force between two objects with mass causes one object to orbit around the other. In tides, the gravitational force between the Earth and the Moon causes the ocean to be pulled towards the Moon, resulting in the tidal bulge.

3. Can EM orbits and tides be affected by other factors besides gravity?

Yes, EM orbits and tides can be affected by other factors besides gravity. For EM orbits, other forces such as air resistance and planetary perturbations can affect the orbit of an object. For tides, factors such as the shape of coastlines and the rotation of the Earth can also affect the tides.

4. How do the strength of electric charges affect the attraction and repulsion in EM orbits and tides?

The strength of electric charges directly affects the strength of the attraction and repulsion in EM orbits and tides. The greater the difference in electric charges between two objects, the stronger the force of attraction or repulsion will be. In EM orbits, this can determine the stability of an orbit, while in tides, this can affect the height and strength of the tides.

5. How do EM orbits and tides play a role in our daily lives?

EM orbits and tides play a significant role in our daily lives. EM orbits allow for satellite communication, GPS navigation, and weather forecasting. Tides impact transportation and trade through the use of ports and harbors, as well as recreational activities such as surfing and fishing. The Moon's gravitational pull also affects the Earth's rotation, which influences the length of our days and the Earth's climate.
