About this document
Harnessing Earth by Adrian Crawford is a document available to read on EtoBox.
The document discusses using coils and magnets more efficiently. It states that when making small magnets with copper wire, only a small part of the magnets from the copper wire enter the steel or iron. It recommends putting the coil in a steel or iron tube so that the tube becomes magnetized with the opposite polarity of the coil core, effectively doubling the amount of magnetism obtained.
