Magnetic Force Microscopy in Liquids [PDF]

open access: yesSmall, 2015
In this work, the use of magnetic force microscopy (MFM) to acquire images of magnetic nanostructures in liquid environments is presented. Optimization of the MFM signal acquisition in liquid media is performed and it is applied to characterize the magnetic signal of magnetite nanoparticles.

Analysis on accuracy of rotor‐locked transient‐response‐based vibration model for switched reluctance machines

open access: yesIET Electric Power Applications, 2022
This paper investigates the accuracy of rotor‐locked transient‐response (RLTR)‐based vibration model for switched reluctance machines (SRM). RLTR is stator vibration stimulated by abrupt change of radial force when turning off one phase of SRM with rotor

MAGNETIC PROPERTIES OF MULTICOMPONENT HETEROGENEOUS MEDIA WITH A DOUBLY PERIODIC STRUCTURE

open access: yesElectrical engineering & Electromechanics, 2020
Heterogeneous media have a wide range of practical applications. Media with a doubly periodic structure (matrices of high-gradient magnetic separators, etc.) occupy an important place.

Analytical investigation of the armature current influence on the torque and radial force in eccentric consequent‐pole PM machines

open access: yesIET Electric Power Applications, 2021
In this work, the electromagnetic torque and the unbalanced magnetic force (UMF) in eccentric consequent pole PM (CPPM) machines are investigated. For this investigation, in the first part of the paper, an exact analytical model is provided for the CPPM ...

3D Magnetic Analysis of the CMS Magnet [PDF]

open access: yes, 2000
The CMS magnetic system consists of a super-conducting solenoid coil, 12.5 m long and 6 m free bore diameter, and of an iron flux-return yoke, which includes the central barrel, two end-caps and the ferromagnetic parts of the hadronic forward calorimeter.

Self-Assembly of Microscale Parts through Magnetic and Capillary Interactions

open access: yesMicromachines, 2011
Self-assembly is a promising technique to overcome fundamental limitations with integrating, packaging, and general handling of individual electronic-related components with characteristic lengths significantly smaller than 1 mm. Here we describe the use

Magnetic forces and DNA mechanics in multiplexed magnetic tweezers. [PDF]

open access: yesPLoS ONE, 2012
Magnetic tweezers (MT) are a powerful tool for the study of DNA-enzyme interactions. Both the magnet-based manipulation and the camera-based detection used in MT are well suited for multiplexed measurements.

Magnetic forces in and on a magnet

open access: yesDiscrete and Continuous Dynamical Systems - S, 2019
Given the shape of a magnet and its magnetization, point by point, which force does it exert on itself, also point by point? We explain what 'force' means in such a context and how to define it by using the Virtual Power Principle. Mathematically speaking, this force is a vector-valued distribution, with Dirac-like concentrations on surfaces across ...

Analytical study of air-gap surface force – application to electrical machines

open access: yesOpen Physics, 2020
The Maxwell stress tensor (MST) method is commonly used to accurately compute the global efforts, such as electromagnetic torque ripple and unbalanced electromagnetic forces in electrical machines.
