Non-Magnetic Metals 1. Aluminum Aluminum isn’t magnetic under normal circumstances, but it does interact with magnets – we call this paramagnetism. This metal isn’t attracted to magnets, so a magnet won’t stick to aluminum. However, when a magnet moves close to aluminum, it causes an electrical field, which interacts with the aluminum. This phenomenon is [...]
What Makes a Metal Magnetic? Magnetism in metals comes from electrons that are unevenly distributed. This distribution creates magnetic dipoles by shifting the charge within the atom back and forth. In magnetic metals, these dipoles align, creating localized magnetic areas, each with a north and south pole. When most localized areas point in the same [...]
Magnetic Properties of Materials: Detailed Explanation According to Ampere’s law, when current flows through a wire or solenoid then magnetic field is produced around it. The magnetism produced by an atom can be due to 2 types of motion of electrons; spin and orbital motion. The net magnetic field created by the electrons in an [...]
Magnetisation and Laws of Magnetism The magnetisation of a material is done by electric current and there are various laws of magnetism to explain. The magnetisation of a material is done by electric current. A material is first magnetised after the magnetic materials are transformed into the required shapes, sizes and designs. Then they can [...]
Magnets in Vedas The ancient Atharva Veda has the reference of some magnet like materials in the treatment of various diseases. Magnet is said to have very ancient origin and its properties were known to the very ancient Aryans. They have the belief that the magnet, besides having the power of attracting iron, was also [...]
Brief Introduction Of Ferrite Core Ferrite core is mainly composed of iron (Fe), manganese (Mn), and zinc (Zn) three metal elements, commonly known as manganese-zinc ferrite. Because the annular ferrite core has no air gap and the cross section area is uniform, the magnetic effect is very high. Ferrite rings have a wide range of [...]
Magnetism as an Energy Source: Understanding Magnetic Force This article will discuss magnetic fields and electromagnetism. An invisible force occurs between two magnets when they are brought close to each other. This force may be an attraction force that pulls the magnets together or a repulsion force that pushes them apart. See Figure 1. Magnetic [...]
Using A Magnet As An Electrical Current Detector An Electric Current Produces A Magnetic Field. You Can Take Advantage Of The Fact To Generate A Simple Apparatus To Check The Electrical Conductivity Of Different Materials, Including Both Solids And Fluids. The Detector Is Composed Of A Coil Of Cable, Using A Magnetic Compass Within It. [...]

Surprising Magnetism: Small but powerful. Can hold up to 20+ piece of paper at one time with just one tiny magnet. The surprising magnetism make even possible to use them in [...]
Magnet Common Sense As we all know, magnets are very useful in our daily life. To let those who are new to the world of magnets have a better understanding of them, in this article, we’ll introduce some common sense of magnets. A Brief History of Magnets The ancient Greeks and Chinese discovered a naturally [...]
Magnetization Dynamics 1 Introduction Magnetization dynamics, where one investigates the time-dependent motion of the magnetization rather than its equilibrium behavior, are fundamental to the properties of magnetic materials. It is worthwhile remembering that the concept of spin waves was introduced by Bloch in 1930 in order to calculate the magnetic contribution to the specific heat [...]
The Basics of Magnetism To understand what makes a material magnetic, you have to think small. Really small. Like atom small. Atoms are the basic building blocks that come together to form molecules, which come together for form, well, just about everything around you! Inside every atom there are protons, neutrons, and electrons. Protons have [...]
