V\u00fdzkumn\u00edci distribuovali 913 \u017een\u00e1m s potvrzen\u00fdm t\u011bhotenstv\u00edm za\u0159\u00edzen\u00ed pro sledov\u00e1n\u00ed \u00farovn\u011b magnetick\u00fdch pol\u00ed a po\u017e\u00e1dali je, aby je nosili nep\u0159etr\u017eit\u011b.

Typick\u00fdmi zdroji magnetick\u00e9ho pole jsou prakticky v\u0161echny elektrick\u00e9 spot\u0159ebi\u010de.
