magnetometer:Device for measuring the strength of magnets or the intensity of magnetic fields. magnitude:Absolute value of a complex quantity (number) without reference to the phase of the quantity.4 Maxwell’s equations:Fundamental equations of electromagnetic field theory: ∇ ×E= −∂B /...
According to standard construction, conventional DC wire rope testers comprise two substantially identical housing sections having strong permanent magnets in each of the housing sections and a search coil located within the tester. In order to use the tester for purposes of checking the strength of ...
In this form it would be of use in motor design calculations. Simpler summary graphs and tables that allow one to get a quick picture of the behavior of Mn-Al-C magnets in general are also included. If the use of this material in motors is seriously considered, more information about ...

CONSTITUTION:When a moving member 7 is moved along a transparent observing window 2, a wiper 6 is moved along the transparent observing window 2 together with the member 7 by the attracting forces of magnets 6b and 7b. In this way, the inner surface of the transparent observing window 2 ...
An MPT consists of a magnetic circuit composed of permanent magnets and coils, and a thin magnetostrictive patch that works as a sensing and actuating element which is bonded onto or coupled with a test waveguide. The configurations of the circuit and magnetostrictive patch therefore critically ...
Testing of actual pulsed magnets to ascertain design change effects of composite reinforcement schemes on the maximum attainable field can be expensive; hence, a standard biaxial testing method is desirable which is relevant to the design of pulsed magnets. In this investigation, an attempt was made...
1. A testing method of a magnetic head, the magnetic head including a pair of hard magnets providing a longitudinal bias field and an air bearing surface, and the testing method comprising steps of: (a) applying a first magnetic field with a constant intensity in a first direction that is...
A coil arrangement for generating a configurable 3D magnetic field vector inside a cavity, comprises a solenoid forming the cavity and having a first axis, a first pair of coils having a second common axis, and a second pair of coils having a third common axis, the three axes intersecting ...
