magnetic properties of earth

The Earth's Magnetism - A magnetic compass was used to help the sailors for navigational purpose. But recently it has been discovered that some migrant birds have magnetic sensors in their heads, which help to guide them using the Earth's magne..

The Earth as a Magnet - About AD1600, William Gilbert, who was a court physician of Queen Elizabeth of England, performed certain experiments using spherical lodestones. When he placed small, pivoted magnetic needles at different positions on this sphere, he found that..

When a bar magnet is suspended freely, it always comes to rest in a north-south direction. This property is used in the construction of a mariner's compas..

By the study if electronic configuration of transition metals it is understood that they generally contain one or more unpaired electrons in the (n-1)d orbital. Due to these unpaired electrons they behave as paramagnetic substances. These substances are attracted by the magnetic field. T..

Magnetism - It is believed that around 2000 BC the Chinese had already discovered the magnetic property of natural iron ore. In a part of Turkey formerly called Magnesia, there are deposits of an iron one which has the property of attracting iron. As this ore..
