Spoofing a passive Hall sensor with fake magnetic fields can inject false data into the downstream of connected systems. Several works have tried to provide defense against intentional spoofing different sensors over last six years. However, they either only work on active or externally injected unwanted weak signals (e.g., EMIs, acoustics, ultrasound, etc.), which spoof output in its linear re...

this paper presents a novel salient pole synchronous generator i.e. permanentmagnet-assisted salient-pole synchronous generator (pma-sgs). due to saturationof conventional synchronous generators (sgs), permanent-magnet-assisted salientpolesynchronous generators (pma-sgs) are presented. pma-sgs are a new type ofsalient-pole synchronous machines with extra permanent magnets (pms) betweenthe adjac...

Superparamagnetic nanoparticles (SPIOs) and magnetic microparticles (MPIOs) are used as contrast enhancers in magnetic resonance imaging (MRI) [1, 2]. Compared to nanofabricated contrast agents, micrometer-sized agents can benefit from higher magnetic moments. As a result, susceptibility artifact (hypointense signal) is increased and visibility improves in MR images [3]. Magnetic moment of a mi...

Context. Dynamos in the Sun and other bodies tend to produce magnetic fields that possess magnetic helicity of opposite sign at large and small scales, respectively. The build-up of magnetic helicity at small scales provides an important saturation mechanism. Aims. In order to understand the nature of the solar dynamo we need to understand the details of the saturation mechanism in spherical ge...

  In this research, a low temperature in-field 57Fe Mössbauer spectroscopy is used for investigation of anomalous magnetic properties of MnZn nanoferrite. Based on Mössbauer spectroscopy results, the reduced saturation magnetization of MnZn nanoferrite in respect to that of bulk sample is due to nonequilibrium cation distribution and spin disorder. The enhanced Curie temperature of MnZn nanofer...
