The IFUSP race-track microtron booster accelerator end magnets antisymmetric perturbations
(Gordon Breach Sci Publ Ltd, 1999-01-01)
We will present measurements and calculations related to the antisymmetric perturbations, and comparisons with the symmetric ones, of the IFUSP race-track microtron booster accelerator end magnets. These perturbations were ...

On a correlation between the ionospheric electric field and the time derivative of the magnetic field
(Hindawi, 2012-02-20)
A correlation of the ionospheric electric field and the time derivative of the magnetic field was noticed over thirty years ago and has yet to be explained. Here we report on another set of examples during the superstorm ...
Inclination of the geomagnetic field measured by an incoherent scatter technique
(American Geophysical Union, 1971-01-01)
A technique to measure the direction of the geomagnetic field by using incoherent scatter techniques is described. The technique has been used to measure the inclination of the magnetic field at the Jicamarca Radar Observatory ...
Design studies of the magnetic properties of structural materials affecting the magnetic field of high-homogeneity superconducting magnets
(2001-12-01)
Austenitic stainless steel presents phase changes caused by heat treatment and welding processes. Because it represents a problem in the design of high-homogeneity magnets, we have been studying the magnetic properties of ...

A test stand to measure the magnetization work of magnetocaloric materials
(Revista De Saude Publica, 2016)
The experimental apparatus presented in this study is capable of precisely measuring the magnetic force produced by a permanent magnets assembly over a magnetocaluric material at a regulated temperature. This data is then ...
Magnetic properties of acicular ultrafine iron particles
(Institute of Electrical and Electronics Engineers (IEEE), 2002-09-01)
Magnetic properties of acicular (similar to60 and similar to200 nm) iron particles, obtained by reduction of alumina-coated goethite particles, are reported. X-ray diffraction and Mossbauer spectroscopy showed that the ...
