Hello! I am a writer currently working on a children's science fiction novel. I need help with a problem of plot that hinges on my main character emitting an EMF field similar to an appliance like a hair dryer. This character is surrounded by this field and needs to get rid of it in a simple way. Now I know that people do not emit EMF fields, but for the purpose of plot this emf field can be read by a guassmeter and is 'stuck' to the character. I need the character to get rid of this field (or deguass, so to speak) and I need a simple way for him to do it. I wanted to know, would taking a bath remove a magnetic field in the same way that water removes static from clothing or hair, or dampens it? Forgive me for my complete amateurish knowledge of physics, writing is more my suit. I would appreciate anyone who could share some thoughts on this with me on this. The solution does not have to be overly complicated but it has to make sense to both a child and a reader with a bit more knowledge of EM Fields than I have, should one chose to read.
