Soft ferromagnetic
Web11 Apr 2024 · Ferromagnetism is a physical phenomenon (long-range ordering) in which certain materials, such as iron, are attracted to one another strongly. Rare earth minerals including gadolinium contain ferromagnets. Magnetism in magnets is caused by one of the most prevalent phenomena observed in everyday life. WebSoft ferrites have lower saturation induction than soft ferromagnetic, yet higher resistivities. Consequently, eddy current losses are much lower; they are usually less than one millionth of those in typical silicon-iron. At frequencies above 10 6 Hz ferrites cores are mandatory. ADVERTISEMENTS:
