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 [...]
Magnetization and Magnetic Intensity We have all played with magnets as children. Some of us even play with them now! But, what makes them ‘magnetic’? Why don’t all the materials and substances possess a magnetic field? Have you ever wondered about it? In this chapter, we will cover the topics of magnetization and magnetic intensity. [...]
Properties of Magnets Properties of Magnets are many. Most prominent property of magnet is that it has two poles and it attracts objects like iron, cobalt and nickel. There are several prominent and noteworthy properties of magnet. It is a known fact that magnet has two poles, namely, north and south, but these two poles [...]
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 [...]
Electromagnetism & Magnetism Applications Magnetism and moving electrons are closely related to each other. The three phenomena pertaining to electromagnetism are: Moving electric charges produce magnetic fields. Magnetic fields exert forces on moving electric charges. Changing magnetic fields in the presence of electric charges cause electrons to flow In 1820, Danish physicist Hans Oersted noted [...]
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. [...]
Novel Magnetic Material Discovered in Meteorite Tens of thousands of tons of meteorites fall to Earth every year. Meteorites first came into existence 4.6 billion years ago and since then they have existed in space without changing their form like “fossils” in the solar system. Research on the history of the solar system has been [...]
Neodymium Adhesive Backed Disc Magnets Buy Adhesive Backed Discs online with MPCO MAGNETS. Self Adhesive Backed Neodymium Disc Magnets! The polarity in the part description identifies the adhesive covered pole face. We have very carefully selected a core range of sizes from our standard Neodymium Disc range which we know are commonly required to be [...]
How Does Temperature Affect Different Magnets? The relationship between magnetic strength and ambient temperature is somewhat complicated. If you are in need of a magnet, however, it is important for you to understand how temperatures affect the strength of different types of magnets before choosing a product. This will allow you to choose the magnet [...]
How Does Temperature Affect Magnetism of Magnets? - Magnets are used in daily life. They’re used in manufacturing, automobiles, security systems and electronics devices. Even the earth itself is a magnet. How does temperature affect the magnetism of magnets? To understand temperature effects, we need to look at the atomic structure of the elements that [...]
