Product Overview & Application Scenarios
High coercive force U-shaped magnet features a customized curved design resembling a horseshoe. These high coercive force U-shaped magnets are widely used for picking up metal objects of various sizes, depending on the magnetic strength of the specific horseshoe magnet. For instance, these high coercive force U-shaped magnets are ideal for collecting items like paper clips, while large industrial-grade horseshoe magnets are commonly applied in construction, engineering, and manufacturing to lift or attract heavy metal components.
Additionally, these magnets can be integrated into customers' products after specialized magnetization, where both magnets on the same side are polarized with one end as the N pole and the other as the S pole to achieve optimal performance.

FAQ
Q1: How do you evaluate irreversible demagnetization risk under dynamic load conditions?
A: It requires analyzing the operating point shift on the B-H curve under combined effects of temperature, external reverse fields, and magnetic circuit geometry. Finite Element Analysis (FEA) is typically used to verify margin against the knee point.
Q2: Why does increasing coercivity often reduce remanence in high-temperature grades?
A: Higher coercivity is achieved by heavy rare earth diffusion (Dy/Tb) or microstructure modification, which increases anisotropy but reduces magnetic moment, leading to lower Br.
Q3: What is the difference between Hc and Hcj in real applications?
A: Hcj (intrinsic coercivity) is the key parameter for demagnetization resistance. A magnet with sufficient Hc but low Hcj may still suffer irreversible loss under reverse magnetic fields or elevated temperatures.
