comparison of air-core and iron-core reactors
... The large stray field of an air-core reactor (Figure 5) may interfere with other electrical equipment. It may heat up steel or aluminum structures and it can even damage concrete buildings due to the steel skeleton within the concrete. Especially closed conducting loops within the stray field must b ...
