Magnetic selection: The magnetic force of general NdFeB and ferrite is so different that it can be several times, dozens of times or even hundreds of times. The iron magnet made of ferrite can absorb a few coins and can already make children exclaim, but the Audi double diamond four-wheel drive chariot uses high-strength neodymium iron boron.
