Clean Earth Magnets Manufactured in Minnesota

Mike Klasco writes about Niron Magnetics' first commercial pilot plant in Minnesota. The opening of this 70,000 square-foot Minneapolis facility took place in October 2024 and is a key milestone in Niron Magnetics's path to scaled production of its Clean Earth Magnet technology and the company’s ability to bridge the acute supply and demand gap for permanent magnets. A significant step forward in the company's mission to produce sustainable, rare-earth-free permanent magnets.

Brane Audio RAD Speaker Technology Named in TIME’s Best Inventions of 2024

As TIME revealed its annual list of the Best Inventions, which features 200 product, technologies and innovations changing our lives, there was a surprising mention of Brane Audio's Brane X portable speaker as a winner in the Entertainment & Gaming category. As audioXpress and Voice Coil readers learned earlier - and coincidently James Croft writes about in Voice Coil November 2024 - the company's Repel-Attract-Driver (RAD) that is part of the Brane X design, is indeed the first effective embodiment of a negative-spring woofer that bends Hofmann’s Iron Law.

Niron Magnetics: Green High-Performance Magnets Get More Green From Samsung

Back in 2020, Barry Vogel, the director of the Audio & Loudspeaker Technologies International (ALTI) Association called me excitedly about Niron Magnetics and about a new magnet material developed from research at the University of Minnesota. Iron Nitride (FeN) was perhaps the biggest news in magnets in 40 years. Composed of common elements — Iron and Nitrogen - the potential of permanent magnets from Niron could be a breakthrough and a game-changer for the audio industry.

First Magnet Powder Presses to Produce Neodymium Permanent Magnets in the United States

Most of us assume that neodymium must only come from China. Yet, rare earth ore is available in California, and reshoring neo-magnet production, including recycling neodymium, is now accelerating in the US. Mike Klasco (Menlo Scientific), tipped off by Salvador Magdaleno (Salvador Consultant), writes about the first manufacturing operation that is ready to deliver neodymium permanent magnets in the United States. This article was written originally for The Audio Voice newsletter.

Next-Generation Rare-Earth-Free Magnets Are Coming

When a speaker development project is initiated, one of the first decisions is usually the magnet type — ferrite or neodymium — each one with its associated benefits, and problems. This article introduces the most promising alternative based on Iron Nitride (FeN), soon be available from Niron Magnetics, and offering the best characteristics of neo, without the supply chain drama, at a price point that rests somewhere between ferrite and neodymium. This article was originally published in Voice Coil, January 2022.
