Top 5 Facts: Natural magnets | How It Works
The most common naturally magnetic mineral after magnetite, some pyrrhotite specimens have a weak amount of magnetism, enough to attract a paper clip. Hematite Often considered to be non-magnetic, atoms within a hematite crystal are seen to align with one another very slightly, indicating a tiny magnetic force.
Permanent Magnets vs Electromagnets | Adams Magnetic Products
An electromagnet is a kind of magnet whose magnetic field is created by the flow of electric current. The magnetic field disappears when the current stops. Electromagnets offer the advantages of controlled holding power and on command release.

The Magnetic Minerals are few, but the property is important because of this fact. Once a specimen is established as magnetic, identification becomes a rather routine exercise. The mineral magnetite is named after this characteristic.. Magnetism occurs (most often) when there is an imbalance in the structural arrangement of the iron ions.
Magnetizing Water - Natural Health News & Remedies
pH and magnetic fields are different things. And the water is not "magnetized" like a magnet. Rather its structure is changed by exposure to a magnetic field. If you have access to laboratory equipment, you will see that the water that has been exposed to a magnetic field has a reduced surface tension.
