There are many ways how magnetism is cause. The main reason is due to the magnetic field of a magnet such as a bar magnet which constantly keeps creating its own magnetic field. And an electromagnet which only creates its magnetic field when it is switched on.
Magnetism is what gives magnets their ability to attract objects made of iron or steel. A magnet creates around itself a region of space with special properties. This region is known as a MAGNETIC FIELD. When two magnets come near each other, their fields create forces that attract or repel. The Earth is itself a huge magnet, and the force its field exerts on other magnets makes them point in a north-south direction. This effect is used in the magnetic compass.
Domains in magnitite or lodestone have to be alligned
No, because Earth's magnetism "flips" about every half million years. When rock form from the cooling lava of volcanoes, the particular magnetic pattern at the time is "frozen" into the rocks. This was evidence that the alternating pattern of the rock has been slowly spreading out as the new crust is formed.

What branch of science studies heat and magnetism
Heating a bar magnet could reduce its magnetism because the heat, by raising the energy level in the metal, disorients the atoms, which disrupts the magnetism.

Magnetic minerals were not formed at the surface

The composition of the magma and the local magnetic flux as it crossed the Curie point.
When current flows in a conductor there is a magnetic field formed around the conductor. This magnetic field can be used to make an electric magnet (like the ones used at junkyards), motors also use magnetism to operate, and many switches (solenoid, motor starters, and relay switches) use magnetism to open or close.
Permanent magnetism is magnetism that is permanent. I think...
No, because Earth's magnetism "flips" about every half million years. When rock form from the cooling lava of volcanoes, the particular magnetic pattern at the time is "frozen" into the rocks. This was evidence that the alternating pattern of the rock has been slowly spreading out as the new crust is formed.
what does magnetism been
Removing magnetism from something is often called degaussing. A degausser uses an alternating current to create an alternating magnetic field that "sweeps" the magnetic fields from things in which they have appeared. The degausser randomizes the magnetic domains that had formed in the metal of the springs.
Magnetism is a force not a solid.
