Man kann auch ohne Messungen an vielleicht schwer zugänglichen Stellen einen Trafo (50Hz) recht schnell als defekt entlarven.

Dazu nimmt man einfach einen möglichst starken Magnet, idealerweise einen Nd-Magnet und hält diesen an den Trafo. Auch beim Leerlauf des Trafos ist ein deutliches Vibrieren des Magneten fühlbar. bei vielen Trafos "tanzt" ein auf ein Gerät (z.B. Uhrenradio) gelegter Magnet hin und her.
