Here we will study about True Dip and Apparent Dip. Apparent Dip India's Best Exam Preparation for Class 12th - Download Now The dip at a place is determined by a dip circle. It consists of a magnetized needle capable of rotation in a vertical plane about a horizontal axis. The needle moves over a vertical scale graduated in degrees. If the plane of the scale of the dip circle is not in the magnetic meridian then the needle will not indicate the correct direction of the earth's magnetic field. T...
Read More →Intensity of Magnetization - Magnetism and Matter Class 12
Intensity of Magnetization represents the extent to which a specimen is magnetised when placed in a magnetising field. Or in other words the intensity of magnetisation is defined as the magnetic dipole moment developed per unit volume when a magnetic material is subjected to magnetising field. Intensity of magnetisation $I =\frac{\text { magnetic dipole moment }}{\text { volume }}=\frac{M}{V}$ India's Best Exam Preparation for Class 12th - Download Now It is a vector quantity whose direction is ...
Read More →Magnetic Induction - Magnetism and Matters Class 12
Magnetic Induction Meaning: The process by which a substance, such as iron or steel, becomes magnetized by a magnetic field. The induced magnetism is produced by the force of the field radiating from the poles of a magnet. Let a uniform magnetising field $B_{0}$ represented by the parallel lines exist in vacuum. When a soft iron bar (ferromagnetic material) is placed inside the field it gets magnetised. The left end becomes Spole and right end becomes N pole. It produces its own magnetic field. ...
Read More →Properties of Diamagnetic Substances - Magnetism and Matters Class 12
Diamagnetic materials are those that some people generally think of as non-magnetic, and include water, wood, most organic compounds such as petroleum and some plastics, and many metals including copper, particularly the heavy ones with many core electrons, such as mercury, gold and bismuth. The substances which when placed in a magnetic field are feebly magnetised in a direction opposite to that of the magnetising field are called diamagnetic substances. Here we will study about the properties ...
Read More →Relation Between Magnetic Permeability and Susceptibility - Class 12 Physics
Permeability is the measure of the ability of a material to support the formation of a magnetic field within itself. In other words, it is the degree of magnetization that a material obtains in response to an applied magnetic field. The magnetic susceptibility is a dimensionless proportionality constant that indicates the degree of magnetization of a material in response to an applied magnetic field. Relative permeability, sometimes denoted by the symbol μr, is the ratio of the permeability of a...
Read More →Difference Between Soft and Hard Magnetic Materials - Magnetism and Matters
Hard magnetic materials are difficult to magnetize and demagnetize, such as tungsten steel, ferrite, neodymium-iron-boron, etc. These materials are easy to magnetize and difficult to demagnetize. They are mainly used as tape materials and permanent magnets. Soft magnetic materials refer to ferromagnetic materials with narrow hysteresis loops, high permeability, low remanence, low coercivity and low magneto resistance. Difference Between Soft and Hard Magnetic Materials are as Follows: Comparison...
Read More →Magnetic Susceptibility and Permeability - Magnetism and Matters
The key difference between magnetic susceptibility and permeability is that magnetic permeability describes the ability of a material to support the formation of a magnetic field inside itself whereas susceptibility describes whether a material is attracted to a magnetic field or is repelled from it. Magnetic Susceptibility Magnetic Permeability Magnetic Susceptibility The magnetic susceptibility of a magnetic substance is defined as the ratio of the intensity of magnetisation to magnetic intens...
Read More →Magnetic Hysteresis - Class 12 Magnetism and Matter
Magnetic hysteresis occurs when an external magnetic field is applied to a ferromagnet such as iron and the atomic dipoles align themselves with it. Even when the field is removed, part of the alignment will be retained: the material has become magnetized. Once magnetized, the magnet will stay magnetized indefinitely. The lagging of intensity of magnetisation (I) or magnetic induction (B) behind the magnetising field (H) during the process of magnetisation and demagnetisation of a ferromagnetic ...
Read More →Magnetic Intensity Definition, Formula - Class 12 Magnetism and Matters
Magnetic Intensity Definition: The degree to which a magnetic field can magnetise a substance or the capability of external magnetic field to magnetise the substance is called magnetic intensity. The magnetic field produced by the external source of current is called magnetising field. The magnetising field depends on external free currents and geometry of current carrying conductor. Magnetic intensity at a point in a magnetic field is defined as the number of magnetic lines of force passing nor...

The substances are weakly attracted by the magnetic field. In the non-uniform external magnetic field, paramagnetic substances move from week field region to a strong field region. A paramagnetic rod sets itself parallel to the field because the field is strongest near poles. properties of Paramagnetic Substance Material are as follows: PROPERTIES OF PARAMAGNETIC SUBSTANCES MATERIAL The substances which when placed in a magnetising field get feebly magnetised in a direction parallel to magnetisi...
