Encyclopedia Magnetica™ <https://www.e-magnetica.pl/doku.php/start> -
https://www.e-magnetica.pl/doku.php/start


*Encyclopedia Magnetica* was started on 25th September 2012 by Dr Stan Zurek
<https://www.e-magnetica.pl/doku.php/user/stan_zurek>, who holds a PhD and
DSc in magnetics-related discipline and is a Senior Member of IEEE
<https://www.e-magnetica.pl/doku.php/wiki/ieee>, Magnetics Society
<https://www.e-magnetica.pl/doku.php/wiki/ieee_magnetics_society> and a
Fellow Member of IET. He has been working for number of years in academia
and industry and authored over 100 scientific and technical publications,
as well as participated in a number of international and UK magnetic
conferences.

Each article is written or verified either by Stan Zurek, or by another
colleague with appropriate degree or experience in magnetics, or a related
field, such as Dr Jeanete Leicht
<https://www.e-magnetica.pl/doku.php/user/jeanete_leicht>, Mr Jeff Jones
<https://www.e-magnetica.pl/doku.php/user/jeff_jones>, or Dr Krzysztof
Chwastek <https://www.e-magnetica.pl/doku.php/user/krzysztof_chwastek>.

All articles are supported by references (listed at the bottom of each
page), which are sources of the factual information, equations, diagrams,
etc. These are: books, peer reviewed papers, PhD theses, or manufacturer
information (for instance if specific devices or materials are mentioned).
