I have zapped my head. I don't know anything about the magnet in the terminator. I've only used the Zapperplans.com Zapper and I know it does not have a magnet. It has helped my sinus headaches and ear aches, zapping your neck for a sore throat helps but I've noticed you have to be consistant and keep at it because it's a harder place to zap. Make sure you do the full three sessions because your head is a nasty place to let out any little guys! Also, I have zapped my face for Acne and cold sores and on my temples for pink eye (it usually goes away in less then a day.) Colloidal Silver helps with these as well. If lymph nodes are swollen, you should zap in that area as well. (making sure you keep zapping if you get sicker) While cleaning up all this stuff, if I've let myself get sick, I'll zap full sessions several times a day until it's all gone. It only takes a couple or three days of diligence!
