We have found that small long-type magnetoelectric (ME) laminate composites of magnetostrictive Tb1-xDyxFe2-y and piezoelectric Pb(Zr,Ti)O3 are quite sensitive to small dc magnetic field (Hdc) variations, when driven by a constant ac magnetic field. The sensitivity limit is Hdc-3 Oe (10-...

The unit of magnetic induction is the tesla (T). The magnetizing force, which induces the lines of force through a material, is called the field intensity, H (or H-field), and by convention has the units ampere per meter (A m−1) (Bennett et al., 1978). The intensity of ...
The unit of measurement for the strength of the magnetic field is A/m (because of the results, A/cm or kA/m are more commonly used), older also Oersted (Oe). Because the magnetic flux density B, measured in Gauss (Gs) or Tesla (T), can be converted using a constant factor, magne...
Dynamic contrast-enhanced MRI (DCE-MRI). In the in vitro measurements in our previous study, the correlation between spin-lattice relaxivity (R1 = 1/T1) mapping and Gd-DTPA concentration was deter- mined using a 7-Tesla MR scanner (Bruker Corp., Billerica, MA, USA)30. In ...

Here, the important question is: how will the cell respond and adapt itself to a high magnetic field gradient? From point of view of physics, the answer is the following. Considering the cell as a droplet of diamagnetic liquid placed in a non-uniform magnetic field, one can conclude that ...
2b) the field is concentrated in a narrow sub-mm region with magnetic field of about 360 kA/m (about 4500 Oe) in the central point between the magnets, while in the face-to-face case (Fig. 2c) the generated field is broadly distributed with respective values of about 440 kA/m (...
magnetic field to a field strength of 40,000 A/cm, switchable in Gauss/Oersted and Tesla. The built-in data logger, the combined digital and analog display as well as the optional data transfer via USB, allows flexible use. Especially at high magnetic field strengths, an absolutely ...
