Description:

Všetky látky, či už nachádzajúce sa v prírode alebo umelo pripravené, majú isté magnetické vlastnosti. Niektoré Z látok však majú význačné magnetické vlastnosti a využívajú sa na špeciálne účely. Tieto látky sa volajú magnetické materiály. Z vedeckého hl'adiska je zaujímavé a užitočné pochopiť magnetické vlastnosti všetkých tried látok — plynných, kvapalných i tuhých a taktiež vytvárať nové materiály, ktoré si pravdepodobne nájdu v budúcnosti praktické využitie., All matter placed in an external magnetic field exhib its magnetic properties. In this article we described the magnetic properties of substances according to their behaviour in an external magnetic field. The group of the substances with disordered magnetic moments is classified as either diamagnetic or paramagnetic depending whether it is repulsed or attracted in an inhomogeneous magnetic field. The group of substances with ordered magnetic moments is classified as ferromagnetic, ferrimagnetic and antiferromagnetic. Ferromagnetic substances are very strongly attracted in an inhomogeneous magnetic field. Their atoms have parallel oriented magnetic moments. Below a certain temperature, the so called Curie temperature, these substances exhibit spontaneous magnetization. Substances with anti-parallel oriented magnetic moments are named ferrimagnetic and antiferromagnetic. Many of these materials have a widespread application in electronics and electrotechnology., Peter Kollár., and Obsahuje seznam literatury
