A new iron magnet — invented in Minnesota — could shrink reliance on China for EV batteries and cell phones

Wang said the Niron magnets are good for about 80% of uses, but he is working at the U on improvements necessary for some high-end technologies like EV motors.
Castilloux said it’s not yet clear what Niron’s magnets are best suited for in an industry with highly specialized needs. Another question is whether they will perform under tough conditions, like high temperatures, for huge vehicle and wind turbine markets or are better for simpler electronics and speakers.
Still the company has powerful investors, including General Motors, Volvo, Samsung, Western Digital and Stellantis. That’s why Castilloux is “cautiously optimistic” about Niron despite the challenges of commercializing new magnet tech. He said those companies likely wouldn’t invest heavily in a company merely for magnets in car speakers.
Niron is also working with the U.S. Department of Defense, which needs magnets for weapons, warplanes, submarines and more.
Castilloux said Niron has a few local competitors planning similar sized-operations for rare earth magnets, and it’s difficult to “come up against China, which is decades ahead on all fronts.” But he said there is enough demand to sustain local production, especially with industry and government support boosting domestic efforts. The U.S. is placing a 25% import tariff of rare earth magnets starting in 2026.
The Niron plant in Minneapolis can produce about five tons of magnetic material per year, and Niron aims to make 1,500 tons at the planned Sartell facility. That’s a small fraction of the more than 200,000 tons of traditional rare earth magnets sold globally last year, according to Adamas data.

On the Wisconsin-Iowa border, the Mississippi River is eroding sacred Indigenous mounds
Bear and other members of her tribe are serving as consultants on the project, as is William Quackenbush, the tribal historic preservation officer for the Ho-Chunk Nation in Wisconsin, and his tribe. They also lead teams of volunteers to help care for the mounds, which includes removing invasive European plants and replacing them with native plants that reduce soil erosion.
Some are skeptical of this manmade solution to a manmade problem. There are some tribal partners who’ve expressed that the river should be allowed to keep flowing as it wants to, Oberreuter said. Snow also acknowledged that people have been hesitant about making such a change to the natural bank.
But, she pointed out, “The bank is (already) no longer what it was.”
When the berm is complete, Snow said, there’ll be a trail atop it that visitors can walk. That may help protect the mounds better than the current way to see them, which is to walk among them, she said.
The Sny Magill Unit has been part of Effigy Mounds National Monument since 1962, Snow said, but it’s not advertised like the rest of the park. That’s in part because there are no staff stationed there to properly guide people through the mounds. But if people visit respectfully, she believes it’s one of the best places to take in the mounds because it’s on a flat, walkable surface, unlike the rest of the park, which is on a blufftop.
Priore criticized his opponents’ stance on TCAAP. “On the one hand, you have two candidates, Kurt Weber and me, with a forward-thinking, fresh perspective and strategic vision,” he said, arguing others want to defer and delay the city’s long-term needs.
Priore listed his other priorities for the city as public safety, and comprehensive planning for more and better trails.
The most recent campaign finance reports do not cover the fall and show little raising or spending for any candidate. Priore’s report indicates he received $600 from Fabel’s campaign fund.
David Radziej was appointed to the Arden Hills City Council in 2022, and has been involved with the city for more than a decade through work on its Economic Development and Finance councils, as well as TCAAP planning groups. He lost a reelection bid in 2022.
In an interview, Radziej raised concerns that the new density limit for TCAAP is out of character for Arden Hills and said he fears adding housing units at the expense of commercial development will harm the city’s tax base.
“I’d like it to be developed. I’d like to hold harmless the current taxpayers,” he said in an interview.
Two months after getting a ticket for being on her phone while driving, a woman was on her phone again when struck a motorcyclist at an Anoka county intersection and killed him, according to a newly filed search warrant affidavit.
The crash occurred on Oct. 5 in Oak Grove at the intersection of Viking and Lake George boulevards NW., the Anoka County Sheriff’s Office said.
The Sheriff’s Office identified the motorcyclist who died at the scene as Kelly Matthew Linder, 49, of Albert Lea, Minn., and the SUV driver as Jessica Marie Pietrzak, 31, of St. Francis. Court records show that Pietrzak was ticketed in August by a St. Francis police officer for driving while on her phone.
According to state Department of Public Safety statistics, distracted driving was a factor in 132 traffic deaths in Minnesota from 2019 through 2023.
Linder was stopped shortly before noon on eastbound Viking Boulevard and waiting to turn left onto Lake George Boulevard when Pietrzak hit the motorcycle from behind, the Sheriff’s Office said.
A search warrant affidavit this week from the Anoka County Sheriff’s Office disclosed that a witness who stopped to help Pietrzak after the crash told law enforcement that Pietrzak said “she was not paying attention and had been on her phone.”
Then as more people stopped to help, Pietrzak “began telling people that the sun was in her eyes, and she did not see the motorcycle,” read the filing, which led to the court allowing investigators to collect data from her cellphone.
The filing pointed out that the sun at that time of the day was not in a position for it to affect her vision. Also, the filing continued, Pietrzak’s entire front windshield has a dark tint. She’s been ticketed twice for that dark windshield in recent years, according to court records.
