Magnetic Materials Magnetism Types The various classifications of magnetic materials take place on the basis of the response provided by these materials when present near a magnetic field. This depends on the level of interaction present between atomic magnetic moments. Sometimes, the interaction is almost negligible, while sometimes, it is quite strong. Hence, these are [...]
Magnetic Materials: Types of Magnetism, Applications, and Origin of Magnetism I feel like every time I learn something about magnetism, I realize that my previous understanding was somehow incorrect or oversimplified. As I’m writing this, I have finished my PhD classes, so hopefully I’m done re-learning magnetic properties. All materials have some form of magnetism [...]
Electromagnetic Spectrum Word Search The electromagnetic spectrum is the collective name of all the different frequencies and types of light or electromagnetic radiation. This electromagnetic spectrum word search has 27 hidden electromagnetic spectrum glossary terms. Search for the hidden words by looking vertically, horizontally, and diagonally. This word search puzzle is designed to fit on [...]
Difference Between Paramagnetic and Diamagnetic The key difference between paramagnetic and diamagnetic materials is that the paramagnetic materials get attracted to external magnetic fields whereas the diamagnetic materials repel from the magnetic fields. Materials tend to show weak magnetic properties in the presence of an external magnetic field. Some materials get attracted to the external [...]
List of Magnetic Metals Magnetic materials are attracted to a magnet and may even become magnetized. Nearly all magnetic materials are metals. Familiar examples of magnetic metals include iron, nickel, cobalt, and steel. But, magnetism is a complex phenomenon. Not all iron or steel is magnetic. There are even some nonmetals that display magnetism! Here [...]
Paramagnetic, Diamagnetic And Ferromagnetic Substances Diamagnetic Substances These substances are weakly magnetized, when they are placed in the external magnetic field, in a direction that is opposite to the applied field. The magnetism that is exhibited by these substances is known as the diamagnetism. The examples of these substances are silver, bismuth, gold, copper, mercury, [...]
Paramagnetic vs Diamagnetic vs Ferromagnetic – Magnetism Diamagnetic, paramagnetic, and ferromagnetic are the three main types of magnetic materials. The terms describe diamagnetism, paramagnetism, and ferromagnetism. The different types of magnetism refer to the way a material reacts to an external magnetic field. Here is a look at these three types of magnetism, examples of [...]
Diamagnetic, Paramagnetic, and Ferromagnetic Materials After reading this section you will be able to do the following: Describe the sources of magnetic moments. Identify the differences between diamagnetic, paramagnetic, and ferromagnetic materials. When a material is placed within a magnetic field, the magnetic forces of the material's electrons will be affected. This effect is known [...]
What are Ferromagnetic Materials After reading this section you will be able to do the following: Define what ferromagnetic materials are. Explain the differences between a permanent magnet and a temporary. Explain why some materials have magnetic properties only when a permanent magnet is near them. In ferromagnetic materials, the magnetic moments of a relatively [...]
Ferromagnetic Materials Ferromagnetic materials are a class of substances that exhibit strong magnetic properties. These materials are characterized by their ability to become permanently magnetized when exposed to an external magnetic field and retain this magnetization even after the field is removed. The term "ferromagnetic" is derived from the Latin word "ferrum," which means iron, [...]
Magnetic Lines of Force Magnetic lines of force, also known as magnetic field lines or magnetic flux lines, are a conceptual tool used to visualize and understand the behavior of magnetic fields. They provide a way to represent the direction and strength of magnetic fields in three-dimensional space. Magnetic field lines are imaginary lines that [...]
The Electric Motor and Magnetism After reading this section you will be able to do the following: Discuss why magnetism is important to the operation of an electric motor. How does magnetism make an electric motor operate? An electric motor converts electric energy into mechanical energy that can be used to do work. In the [...]
