Ano, permanentn\u00ed magnet m\u016f\u017ee generovat elekt\u0159inu, kdy\u017e se pohybuje vzhledem ke c\u00edvce, na z\u00e1klad\u011b principu elektromagnetick\u00e9 indukce.<\/strong><\/p>\n

Ne magie, jen fyzika<\/h3>\n

Magnety samy o sob\u011b elekt\u0159inu nevytv\u00e1\u0159ej\u00ed. Pot\u0159ebuj\u00ed pohyb. Kdy\u017e se magnet pohybuje bl\u00edzko vodiv\u00e9ho dr\u00e1tu, zp\u016fsobuje pohyb elektron\u016f \u2014 to je elektrick\u00fd proud.
