According to the invention, a stray field collector is brought into a stray field of the power transformer, whereby a voltage is generated.
The magnetic trap (30) according to the invention is characterized by an especially low magnetic stray field and has a very homogeneous and especially strong magnetic field.
The spatial area comprises an arrangement which is designed to absorb the high frequency stray field.
The invention relates to a low stray field magnetic trap (30) for capturing electrons for an X-ray detector (24), and an X-ray detector (24) comprising the magnetic trap (30), in particular of the EDX type.
Consequently, the gradient magnetic field can be increased without increasing the leak field.
It is detected whether the leakage field is a bias magnetic field of which polarity by using an adjustment magnetic field as a correction bias.
To reduce the magnetic field strength in the CRT environment a magnetic compensation field which is counterdirected to the leakage field is generated.
The deflecting coil generates a magnetic deflecting field (B) for the electron beam and a magnetic leakage field (BL) in the CRT environment.
The invention also relates to an antenna assembly, in particular for reducing the uplink stray-field losses in a mobile radio system.
The main magnetic circuit (5a..5j) and/or the leakage field guide components (6a..8c) consist of a magnetically isotropic material.
The invention is based on registration of the magnetic leakage field of the article by visualization of the distribution of magnetization in a magneto-optical film which is placed near the surface of the article.
The leakage field is composed of a dipole field and a quadrupole field.
