How is gravity and magnetic field of celestial objects created?

Why does the earth spin and revolved around the sun? The basic reason why the planets revolve around, or orbit the sun (rotate actually is used to describe their spin, for example, the Earth completes one rotation about its axis every 24 hours, but it completes one revolution around the Sun every 365 days), is that the gravity of the Sun keeps them in their orbits. Just as the Moon orbits the Earth because of the pull of Earth’s gravity, the Earth orbits the Sun because of the pull of the Sun’s gravity. Is it true that the spinning of tons and tons of molten iron and nickel produces magnetic field? Motions of molten metals in the Earth’s core generate our planet’s magnetic field. Movement of molten iron and nickel generates electrical and magnetic fields that produce Earth’s magnetism. if the earth would stop spinning and stop revolving? The probability for such an event is practically zero in the next few billion years. Assuming it did happen only the people at the poles would be safe

Gravity is caused by gravitational interaction, possibly gravitons, but due to the natural duality of particles and waves, also by the curvature of time and space (electromagnetism is caused by fluctuations in the electromagnetic field, AND photons, and gravity by fluctuations in the spacetime-field, AND gravitons). These gravitons (or the perturbations in space-time) travel at the speed of light, and are emitted by all particles. Thanks to quantum mechanics, you can also be hit by a billionth of a particle and receive a billionth of the effect, so all mass attracts all mass as gravitons emitted by all mass hits all mass, and vice versa at exactly the same time. The magnetic field is caused by a rotating electrical charge. In case of the Earth, the core is slightly charged and rotates (because the entire Earth rotates). Thus, we have a magnetic field. The same goes for the sun. The Earth spins due to the conservation of angular momentum. Just like regular momentum, angular momentum (re
