Paleomagnetic dating utilizes records of "how things were" in a given area across time in the past as a basis for comparison to an unknown sample in order to date it. A link is provided to the Wikipedia article on paleomagnetism, which is the basis for paleomagnetic dating.
Paleomagnetism basically works by comparing old data with new data. They compare record history of the direction and intensity of the magnetic field of the Earth with new data just received.
The principle that Bullet Train work on is Magnetic levitation and magnetic suspension. . .
It uses magnetic power to heat the food more evenly.
Magnetic bracelets work according to the placebo effect. I f you think they work then they do. Magnetic bracelets are harmless but no serious scientific study has revealed any effect other than the (important) placebo effect.
yes
Yes, if you do it right.
Why not? the desert is just the same as any other place on planet earth. Magnetic compasses work fine in the desert. See the "Where does the magnetic compass not work?" question for some places where they don't work.
They work by using a magnet.
There are still magnetic fields in space - especially if you remain close to Earth. But magnetic compasses are usually designed to use gravity, which you won't have if you are in free fall. A specially-designed magnetic compass would work, though.
No, the sun does not have an iron core to generate magnetic poles

No, they are silly.
Magnetic lasso makes selections, it snaps to edges automaticaly while you work with this tool.
Digital information is stored in microscopic needles as part of the disk's magnetic coating.
