Does the brain really have a magnetic field? The deceased relatives gave their families dreams. I heard that although my loved ones passed away. But the magnetic field is still there?

The human brain does have a magnetic field, but the most common one is electromagnetic wave.

Physiologically speaking, the human body is composed of various elements, which will dissolve after death, so it is naturally impossible to leave anything behind.

Biologically, the body is completely decomposed by microbial colonies, and there is basically little left. Then, after death, the corresponding magnetic field disappears.

The so-called family dream is just a spiritual connection caused by missing.

We all know that electromagnetic effect, magnetism and electricity are basically an interactive relationship. When brain waves interact, they can also produce magnetic fields, but they cannot be described by simple giant magnetic fields.
