this is one of a number of things needed for the hyper dimensional resonator said to be 7 layers of 21 awg=21 American wire gauge wire. on a 7 inch long core, I've made a number of them but I used a 8 inch long core and I made pvc spacers to space the coil for the length of 7 inches this way the round spacers makes it very easy to roll wire onto the core , mild steel core was the best and iron core just kept burning out the 3 amp safety fuse , I didn't have soft iron and nothing like the ferrite type cores just some kind of solid looking iron so I have several hdr electromagnets and only 2 are iron types and replacing the 3 amp fuse with higher current rating fuses can fix the burnout problem when useing solid iron bars for the former in an electromagnet , I have 7 layered electromagnets and 7.8 layered in reference to the 7.8hz Schumann resonance, and 7.5 layered in reference to the brain wave frequency, which some may say its 7.8 but who knows for sure and I have found...
