properties of magnetism magnetism

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..

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..

The ultimate source of magnetism is the magnetic dipole moment, associated with an atom due to orbital motion and intrinsic spin. This suggests that all substances possess magnetic property as energy material consists of atoms having electrons revolving..

Single touch method - Place the soft iron piece AB flat on a table and stroke it with a bar magnet from A to B with one end of a bar magnet as shown in figure. When the magnet reaches B it is lifted, and brought back to A to repeat the stroke. After a few strokes you w..

Magnetic properties of Steel and Iron - Iron gets magnetized faster but loses its magnetism as soon as the inducing magnet is removed. Hence soft iron is said to have high susceptibility but low retentivity. This property of soft iron is v..

Iron gets magnetized faster but loses its magnetism as soon as the inducing magnet is removed. Hence soft iron is said to have high susceptibility but low retentivity. This property of soft iron is very useful in making temporary electromagnets where we need ..
