Magnetic susceptibility is the extent to which a material can be magnetized in an external magnetic field. Materials displaying diamagnetism are weakly repelled by a magnetic field. For instance, gold, copper, and mercury are diamagnetic materials. 2. Paramagnetism: When materials are weakly attracted by a strong magnet, they exhibit …

Within an atom, every electron travels in an orbit and spins on an internal axis. Both types of motion produce current loops and therefore magnetic dipoles. For a particular atom, the net magnetic dipole moment is the vector sum of the magnetic dipole moments. Values of μ for several types of atoms are given in Table 12.8.1.

Magnetic Raw Materials. All the permanent magnets in the world are currently made from five types of material each with very different characteristics. The five types are, alnico, ferrite, flexible rubber and the rare earth magnets samarium cobalt and neodymium. Read on to find out about each raw material, how the types of permanent magnets are ...

Ferromagnets. Only certain materials (e.g., iron, cobalt, nickel, and gadolinium) exhibit strong magnetic effects. These materials are called ferromagnetic, after the Latin word ferrum (iron). A group of materials made from the alloys of the rare earth elements are also used as strong and permanent magnets (neodymium is a common one).

Magnetic materials are important materials for high-tech areas and technological development, which are being classified not only based on their origin but also by the nature of processing, properties, functions, and applications. This book presents an overview of the different types of new magnetic materials and hybrid structures that …

Magnetism - Magnetic Fields, Forces, Materials: All matter exhibits magnetic properties when placed in an external magnetic field. Even substances like copper and aluminum that are not normally thought of as having magnetic properties are affected by the presence of a magnetic field such as that produced by either pole of a bar magnet. Depending on …

Magnetic materials are always made of metal, but not all metals are magnetic. Iron is magnetic, so any metal with iron in it will be attracted to a magnet. Steel contains iron, so a steel ...

Fig. 37–13. Relative orientation of electron spins in various materials: (a) ferromagnetic, (b) antiferromagnetic, (c) ferrite, (d) yttrium-iron alloy. (Broken arrows show direction of total angular momentum, including orbital motion.) We would now like to discuss some of the more exotic magnetic materials.

List of Magnetic Materials. Following is the list of magnetic materials available in the market. Diamagnetic Metals. Ferromagnetic Metals. Paramagnetic Metals. Water. Gold. Mercury. Salts of Iron and Nickel.

Magnetic Materials and Classifications. The elements found in nature that are attracted by a magnet are referred to as magnetic in nature. Typically, they can be magnetized so that they behave as magnets themselves. Most permanent magnets that currently exist are known to be made of five types of material: ferrite, alnico, flexible …

Magnetically hard materials are used to create permanent magnets made from alloys generally consisting of varying amounts of iron, aluminium, nickel, cobalt, and rare earth elements samarium, dysprosium, and neodymium. The strongest permanent magnets are known as neodymium magnets and are made from an alloy of neodymium, iron, and boron.

magnet, any material capable of attracting iron and producing a magnetic field outside itself. By the end of the 19th century all the known elements and many compounds had been tested for magnetism, and all were found to have some magnetic property.The most common was the property of diamagnetism, the name given to …

Ferromagnetism is the basic mechanism by which certain materials (such as iron) form permanent magnets. This means the compound shows permanent magnetic properties rather than exhibiting them only in the presence of a magnetic field (Figure 14.2.1 14.2. 1 ). In a ferromagnetic element, electrons of atoms are grouped into domains in which each ...
