Magnets Are Weird In this article, we discuss a few things that might make you question what you think you know about magnets. We’ll show magnets stronger at the edges than at the center. We'll see magnets that won’t attract to center upon one another. We’ll even make the north pole of one magnet stick [...]

Unlike traditioinal sinter neodymium magnets, Hast neodymium magnets can keep less weightlessness value and excellent anticorrosion than common neodymium magnets. Hast Testing Conditon: Test atmosphere:3atm Test humidity:95% Test [...]
Piezo and Magnetic Buzzers Buzzers are among the most versatile sound components available today. Add the fact that they are low cost, high quality devices and it’s easy to see why they are being designed in by everyone as the goto audible notification device in phones, cars, kitchen appliances and everything in between. There are [...]
Piezo Buzzers vs. Magnetic Buzzers — What’s the Difference? Piezo vs Magnetic Buzzers Communicating information from a product to its end user is a necessary task across many industries — from home appliances and security devices to automotive electronics and office automation devices, audio signals are a necessity. These audio signals can be generated using [...]
How to Increase the Strength of an Electromagnet Electromagnets work just as well as permanent magnets. In fact, they are even more useful, because you can turn them on and off. You'll find electromagnets in hard drives, speakers and even in sophisticated equipment like MRI machines. You obviously need a stronger electromagnet for a particle [...]
Electromagnetic Induction Voltage applied to a conductor creates a magnetic field around that conductor. It is possible to reverse this process and for a magnetic field to generate a voltage in a conductor. For this to occur, there must be some relative motion between the conductor and the magnetic field. Electromagnetic induction takes place whenever [...]
What Are The Most Common Materials For Magnetic Cores? As we know, the inductor core materials there are many the main iron core, silicon steel sheet core, FeSiAlF core, Mn Zn ferrite core, Ni Zn ferrite magnetic core core. Among them, Mn Zn ferrite core, Ni Zn ferrite magnetic core are ferrite cores. Do you [...]
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 [...]
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 [...]
Magnetic Jewelry an Overlooked Danger The federal government brands magnets in toys a deadly hazard to children because the tiny, powerful objects can fall out and cause serious, even fatal, internal injuries when swallowed. Yet the Consumer Product Safety Commission has not taken steps to regulate even more powerful magnets when they are sold in [...]
Magnetic Core Memory Ever thought of the origin of the phrase "Core Dump"? Even today, programmers know that it means a dump (to disk or hard copy) of the contents of part of memory. And no, the phrase does not mean that it's a "central" part of memory; it means Cores, literally. Like these. The [...]
