Many people 'coaching' have no idea what coaching is as they haven't been trained or haven't been coached by a professionally trained and credentialed coach. There are 'schools' that will offer a credential after three hours of training and people read a book or watch a TV program and decide 'I'm a coach!'.
The most magnetic and common type is a lodestone. It consists of a brownish-black mineral called magnetite. Lodestones are natural compasses: Suspend one by a thread or wire and it will rotate until its magnetic field is aligned with Earthâs magnetic field. A magnetic field is the area around a material in which its magnetic forces can be detected.
Only a small amount of the magnetite on Earth is found magnetized as lodestone. Recent research has found that only a variety of magnetite with a particular crystalline structure, a mixture of magnetite and maghemite, has sufficient coercivity to remain magnetized and thus be a permanent magnet.here Is It Found Lodestone and other magnetic iron ores often occur in igneous and metamorphic rocks found around the world. Countries of origin are the USA, Canada, India Mexico, Romania, Italy, Finland and Austria.
