The magnetic susceptibility in soft magnetic composite materials [PDF]
Le Journal de Physique IV, 1998 The paper gives a demonstration of an analytic law which correlates the " effective " susceptibility in composite magnetic materials with the volume fraction in magnetic matter. The relation is built round two basic parameters : the first characterises the nature of the magnetic substance through an intrinsic susceptibility supposed to only be ...

Shape programmable magnetic pixel soft robot
Heliyon, 2022 Magnetic soft robots (MSRs) can achieve controllable shape-morphing by magnetic programming to the magnetic elastomer. However, the magnetization profile is usually implemented on a continuous region and is unchangeable.

Loss separation in soft magnetic composites [PDF]
Journal of Applied Physics, 2011 We report and discuss significant results on the magnetic losses and their frequency dependence insoft magnetic composites. Two types of bonded Fe-based materials have been characterized atdifferent inductions from dc to 10 kHz and analyzed by extending the concept of loss separation and the related statistical theory to the case of heterogeneous ...

Reprogrammable liquid-metal/NdFeB/silicone composite magnetic elastomer
AIP Advances, 2023 Programming the patterned magnetization profile on the magnetic elastomer can enable the magnetic soft robot to produce controlled deformation. But the magnetization profiles are usually unchangeable, which leads to the single function of magnetic soft ...

Sintered Lamellar Soft Magnetic Composites: Shaping and Magnetic Properties
Materials Science Forum, 2012 Sintered lamellar soft magnetic composite (SL-SMC) is a promising material for power frequency applications and for all types of electric motors, including induction motors. Alumina coated Fe-3%Si particles cut from steel sheets offer both the advantages of standard laminated steel products, and of soft magnetic composites (SMC).
