of a of the riesen magnet resistance element (r1, r2, r3, r4) detected change of the magnetic field; and– a on the input side of the integrated circuit (23) provided in the protective resistor (r5) and a on the output side of the integrated circuit (23) provided in the protective ...
This paper presents a new method which can not only measure the magnitude but also the direction of the magnetic field. A structure with a cantilever driven in different modes is used. The magnetic field direction and magnitude are detected by measuring the vibration amplitudes of the different ...
The direction of the easy axis of magnetization in γ' -FeN has been determined by detailed analysis of certain peaks in the Mössbauer spectrum of a powdered sample in an applied magnetic field. The analysis indicates the magnetic-easy-axis direction to be along . The electric field gradient...
To solve the problem, we need to analyze the behavior of a rod suspended in a magnetic field and determine whether we can conclude the direction of the magnetic field based on the orientation of the rod.1. Understanding the Orientation
THE determination of the direction of the resultant force, at any point, due to a long, thin magnet, is of some importance as a laboratory exercise, and it is necessary to be able to compare the direction which a small needle takes up in its field with the theoretical direction. For ...
in our article,The Earth Is a Magnet.) Diametrically magnetized magnets will tend to wobble, as if the magnet weren't perfectly round. What you're actually seeing is the magnet's tendency to align with the earth's magnetic field. Axially magnetized magnets won't show this sort of wobble....
Magnetic field sensor device for detecting the stroke of movable components That the three-dimensional component of the magnetic field of the magnet type which is provided in the configuration component which exercises, the stroke which it tries will detect in the direction of the component, extendin...
High-field magnetization measurements on Er[sub 2]Fe[sub 17] single crystals If the easy magnetization direction of a 3d-4f ferrimagnet is perpendicular to a high-symmetry axis, a magnetic field applied in the easy direction may ind... MD Kuz'Min,Y Skourski,KP Skokov,... - 《Physical...
