| Magnetite is the most magnetic of all the naturally occurring minerals on Earth.[4] Naturally magnetized pieces of magnetite, called lodestone, will attract small pieces of iron, and this was how ancient people first noticed the property of magnetism. Lodestones were used as an early form of magnetic compass. Magnetite typically carries the dominant magnetic signature in rocks, and so it has been a critical tool in paleomagnetism, a science important in discovering and understanding plate tectonics and as historic data for magnetohydrodynamics and other scientific fields. The relationships between magnetite and other iron-rich oxide minerals such as ilmenite, hematite, and ulvospinel have been much studied, as the complicated reactions between these minerals and oxygen influence how and when magnetite preserves records of the Earth's magnetic field. shipping insurancehome security companies | |

| The Rolling Stones are an English rock band formed in London in April 1962 by guitarist and harmonica player Brian Jones, pianist Ian Stewart, vocalist Mick Jagger and guitarist Keith Richards. Bassist Bill Wyman and drummer Charlie Watts completed the early lineup. Rhythm and blues cover songs dominated The Rolling Stones' early material; they are credited for raising the international regard for the more primitive blues typified by Chess Records' artists such as Muddy Waters who wrote "Rollin' Stone", the song after which the band is named. Unconcerned with being authentic blues stylists, from the start the Rolling Stones have played rock and roll, and have written and recorded in many genres.[1] Medical Marijuana Dispensarypainful heel | |
