although the promotional effects on bone healing of pulsed electromagnetic fields (pemf) have beenwell demonstrated, the effects of static magnetic fields (smf) remained unclear. in this study, effects of acustom-made magnetic wrap on radiographic and histopathological aspects of bone healing using a canineunstable osteotomy gap model were investigated. after an osteotomy of the midshaft radius...

The purpose of this paper is to present a new type of dynamic balancing system, having a driving solution of the rotating part based on magnetic interactions. The magnetic system also plays the role of an elastic bearing. In the first part of the article is presented the technical solution which allows the dynamic balancing evaluation depending on the radial displacement between two disks with ...

This paper presents the effect of centrifugal load in functionally graded (FG) hollow sphere subjected to uniform magnetic field. Analytical solution for stresses and perturbation of the magnetic field vector are determined using the direct method and the power series method. The material stiffness, the magnetic permeability and the density vary continuously across the thickness direction accor...

The magnetic sail is a quite new concept of space propulsion utilising the solar wind in order to transfer momentum to a magnetic field source. The magnetic field size can be increased significantly by injecting a plasma into the center of the magnetic bubble. This concept is called Mini-Magnetospheric Plasma Propulsion (M2P2) system. The plasma injection shall create a magnetosphere with a dia...

Electromagnetic field probes inevitably change the original field distribution to some extent when they are positioned close to a device. That change affects measurement accuracy and the device operation. We have developed optical magnetic field probes, which comprise a loop antenna element and an electro-optic crystal, to perform magnetic nearfield measurement with high accuracy in the GHz fre...

We show, with direct numerical simulation of three-dimensional magnetohydrodynamic turbulence with a mean magnetic field, B, that the time behavior of the dynamo α-effect is constrained by the dynamics of magnetic helicity. A time-scale tc is introduced such that for t < tc, the α-coefficient calculated from the simulation is close to the result given by Field et al (1999), αFBC ∼ − τc 3 (〈v · ...

In this paper, a new electromagnetic actuation system is presented for magnetic nano-particles based targeted drug delivery. The system is composed of three sets of coils; each set contains two parallel coils that can generate the oriented 3D magnetic gradient field. Differential Current Coil approach is used to calculate the applied current to each coil to ensure that the gradient field, gener...

The small dimensions of the on-chip interconnect structures provide the interesting opportunity of using the optimized model of dominant magnetic field even at very high operating frequencies for inductance and resistance extraction. The parameters are obtained from the field energy calculated from the magnetic field distribution in the simulation domain. Vector and scalar shape functions are u...

Atomic magnetometers have found widespread applications in precise measurement of the Earth’s magnetic field due to their high sensitivity. In these measurements, various methods have been utilized to compensate the Earth’s magnetic field in an unshielded environment. In this paper, we have proposed a method based on finding the minimum resonance frequency (corresponding to minimum magnetic fie...
