Ηλεκτρισμός

(Ελληνικά)

Ο ηλεκτρισμός είναι ένας «γενικός» όρος. Περιλαμβάνει τα «ηλεκτρικά φαινόμενα», δηλαδή ένα σύνολο από φυσικά φαινόμενα που σχετίζονται με την παρουσία και τη ροή ηλεκτρικού φορτίου. Ο ηλεκτρισμός συνδέεται με μια ευρεία ποικιλία από πολύ γνωστά φαινόμενα, όπως οι αστραπές, ο στατικός ηλεκτρισμός, η ηλεκτρομαγνητική επαγωγή και το ηλεκτρικό ρεύμα. Επιπρόσθετα, ο ηλεκτρισμός μαζί με τον μαγνητισμό αποτελούν την ενιαία έκφραση του ηλεκτρομαγνητισμού, μιας από τις τέσσερις θεμελιώδεις αλληλεπιδράσεις, και μαζί επιτρέπουν τη δημιουργία και τη μετάδοση της ηλεκτρομαγνητικής ακτινοβολίας, όπως για παράδειγμα τα ραδιοκύματα. Τα ηλεκτρικά φορτία παράγουν ηλεκτρομαγνητικά πεδία, που αλληλεπιδρούν με άλλα ηλεκτρικά φορτία.
