Why don't we use the magnetic field provided by the earth to generate electricity? It sounds like a good idea, but it's not very practical. Before we explain why, let's understand how we generate electricity, in case anyone reading this doesn't already know. Electricity (we say "current") is created when charged particles flow, like water [...]
Scientists design new magnets to provide room for sustained nuclear fusion reactions Scientists are working to realize the potential of nuclear fusion as a nearly inexhaustible source of clean energy, one of the ways that is through new and improved magnets that confine the fields of plasmas so that key reactions can occur . A [...]
Magnets Generate More Electricity in Generators Purdue University researchers have developed a parallel arrangement of inner magnets to reduce size and increase the efficiency of low- to medium-power generators. Source: Purdue University Generators have many uses, from cars to airplanes to microgrids. There is currently a strong desire to reduce size and increase efficiency of [...]
GreenSpur, Niron Develop Rare Earth-Free Power Generation Solution GreenSpur Wind and Niron Magnetics have announced a new rare earth-free power generation solution for the offshore wind market. The findings have been validated by ORE Catapult, the UK's innovation and research center for offshore renewable energy technologies. “Existing turbines use radial flux generators and current designs [...]
Amazing! Ectricity Can Be Generated by Magnets Unexpectedly, a magnet and a gyro can design a chic table lamp. This table lamp called iface is equipped with a copper ring. When the magnetic gyro rotates on the top cover, it will light up the bottom. The LED light, since the iface contains an oily liquid, [...]
Intriguing Properties and Applications of Functional Magnetic Materials Abstract Functional magnetic materials, also called the smart materials of the future, are a group of materials having important and interesting physical properties, which can be affected when an external magnetic field is applied. They are intriguing models that have a strong impact on improving different technologies. [...]
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 [...]
What Objects Are Attracted To Magnets? Magnets are very useful in our lives. For example, we can use magnets to attract iron nails, iron keys, and iron scraps, etc. So in addition to these objects that are obviously composed of iron, what other objects can be attracted to magnets? First of all, let us first [...]
Magnetic vs Non-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 [...]
List of Magnetic Metals What Metals Are Magnetic? Magnetic metals include some pure metallic elements and their alloys. Here is a list of some of the most magnetic metals: Iron Nickel Cobalt Gadolinium Dysprosium TerbiumSome types of steel (e.g., ferritic stainless steel) Neodymium, iron, boron alloy (Nd magnet) Even though both iron and nickel are [...]
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 [...]
