Earth's magnetic field reverses over time; the changes show that seafloor has taken place over time.
Magnetic particles suspended in liquid magma align themselves with the Earth's field, and when the magma solidifies they retain that alignment even after the direction of the Earth's field changes. So, for instance, as magma spreads outward from the Mid Atlantic ridge, you get a series of magnetic strips of varying alignment as you move outward, and the strips on the west side correspond with those on the east side.

Yes, a particle used in a particle accelerator must have a charge to be useful in the device. Particle accelerators we use in high energy physics to investigate things all work by applying a moving or shifting magnetic field to accelerate charged particles. We speed these particles up by repeatedly "hitting" them with a magnetic field. Uncharged particles will not respond to this, and canot be used in the devices.
The Earth's Magnetic shield is important for preventing the Atmosphere from being destroyed by solar wind by deflecting dangerous particles from impacting the Earth.It protects Us from the magnetic / electrical radiation that comes from the Sun. High radiation periods coincide with solar storms.It protects us from solar radiation (wind) from the sun
Magnetic paint is just like regular latex paint, except for the fine particles of iron dust mixed throughout which gives it a special magnetic quality. When applied to a surface, you end up with a layer of primer with many tiny flecks of iron spread throughout. Magnets are attracted to these flecks of iron transforming your project into a magnetic surface.
A non-magnetized piece of iron would capture the magnetic particles.
Magnetic separation is technique used in metallurgyfor the concentration of ore particles. The principle of this method is that the magnetic ore particles can be separated from non magnetic impurities (gangue) or viceversa.
The deflection of a magnetic compass in the presence of an electric current, is evidence that an electric current produces a magnetic field.
if charge particle is in motion ,then it has magnetic field
