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.
We call these natural magnets lodestones. Until about two hundred years ago, people made magnets by finding a lodestone and rubbing iron on it. The rubbing lined up the electrons of the iron so that all the electrons would pull in the same direction. But today we can use electricity to make magnets.
