Magnetism can only significantly affect materials that are themselves significantly responsive to magnetic fields such as charged particles and ferromagnetic materials.

Magnetic forces can both attract and repel, but gravity can only attract.

There are lots of magnetic forces at work within you and around you, but the net effect of all those magnetic forces, some attracting and some repelling, is to achieve an overall condition of being pretty much magnetically neutral. Gravity, on the other hand, is always attracting.

The sum of all the magnetic forces at work within you is extremely small, so small that you can for most purposes say that it’s zero. That is why when you let go of your salad fork it doesn’t stick to your hand, and why you’re not collecting magnetic filings on your body while you play in the sand at a beach.

On the other hand, it’s gravity, always attracting things, that keeps you, the salad fork, the sand, the ocean and the atmosphere above you stuck firmly to the Earth beneath your feet.

At interplanetary, interstellar and intergalactic distances, gravity rules.

Regarding the tidal forces on the moons of Jupiter – yes, there is an exchange of energy. The tidal stresses and deformations experienced by these moons (and indeed by our Moon from Earthly tidal forces) represents a transfer of angular momentum. It’s a complex exchange of energy between planet and moon, but the bottom line is that the tidal energy that deforms a moon in orbit around a planet comes at the expense of the rotational energy of the planet. Tidally deforming an orbiting moon makes the planet spin a tiny, and I mean REALLY TINY, bit slower. It’s not free energy.

In the weightless vacuum of space gravity will always try to squeeze matter in on itself, and a sphere is the shape that permits matter to occupy the smallest possible volume.

In the case of a gas in otherwise empty space, gravity will collapse the gas in on itself and evenly distribute the mass into the smallest possible volume. Absent any external forces to change this arrangement, the gasses will be most compressed at the center of the spherical volume and the least compressed at the surface of the spherical volume.

For rocky objects smaller than a hundred miles or so, such as many asteroids, gravity lacks the power to compress the mass of the object into a sphere and so we’re left with lots of lumpy, potato and peanut-shaped asteroids.

When a lump of rock in space is larger than a couple of hundred miles in diameter, such as the minor planet Ceres, gravity is strong enough to produce a spherical shape.

Soap bubbles don’t experience much shaping due to gravity, but they do experience an analog of gravity, which is the surface tension of the soap film. Again, it’s all about natually distributing matter to achieve the smallest possible volume for the air surrounded by the soap film – which is a sphere.

Isn’t the most basic governing law that everything seeks balance in the most energy efficient manner possible. The spherical shape does this because it is the most symmetrical form in existance. Planets are spherical because the creation process is the same process that governs all physical free forming construction?

We do accept applications for part-time employees that are 16 years and older. However, for this job fair, we’re looking to hire age 18 and older as employees will be working past 10 p.m. in the evenings.

Magnetism is almost infinitely stronger than gravity.

Could a pyramid shaped Neodymium magnet maintain its non spherical shape if it were 50 meters tall * 50 Meters wide * 50 meters long?

The reason I ask is because 2 tiny magnets pull on each other so forcefully. Do magnets pull within themselves too?

Question 2:

One of Jupiter’s moons is in a very elliptical orbit, so it experiences great internal squeezing (and heat generation) when it hits the pointy parts of its orbit. Does this make the orbit decay or is it free energy?
