Bruker Magnet The electromagnet in the Magnet Laboratory consists of a Bruker Magnet B-E 15, and a Heinzinger PTN 125-40 magnet power supply. These can be used to generate magnetic fields of up to about 1 Tesla. The field strength depends on the current and the distance between the poles of the magnet (Air gap). [...]
Commonly Used Soft Magnetic Core Iron Powder Core Permalloy Powder Core Iron-Silicon-Aluminium Powder Core Magnetic powder core is a kind of soft magnetic material made by mixing and pressing ferromagnetic powder and insulating medium. Ferromagnetic particles are very small (0.5-5 micron used at high frequencies) and are separated by non-magnetic insulating film materials. Therefore, on [...]
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. [...]
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 [...]
Handling Neodymium Magnets Safety Precaution With high intrinsic coercive force (Hci) over 12,000 Oe and maximum energy product ((BH)max) between 27-52 MGOe, neodymium magnets have the greatest strength among all available permanent magnet materials (>7 times stronger than ceramic magnets) as they are extremely resistant to demagnetization and have high saturation of magnetization. The magnetization [...]
THE PURPOSE OF A PERMANENT LOAD LIFTING MAGNET With the help of a permanent load lifting magnet one can lift, move, place and transport ferromagnetic objects, as well as round or flat material. The pieces can be flat or cylindrical. The transport of round parts can also be carried out by means of a V-shaped [...]
How to keep the magnet magnetism for a long time? Magnet, also known as permanent magnets, are objects that exist around the material and have their own magnetic fields. They are both natural and artificial. Artificial magnets are usually made of a metal alloy and have strong magnetism. Ferromagnetic refers to the magnetic state of [...]
How do magnet manufacturer handle magnets? Many people know magnets and learn to use them. They also know that magnets are widely used in society. So, how do magnet manufacturer handle magnets? Let me introduce some measures for magnets from magnetome magnet manufacturers. First, the magnet is demagnetized. The magnet manufacturer uses the external magnetic [...]
