yes electric impulses are created in the nervous system.
Human electricity energy is generated by chemical processes in nerve cells. Billions of nerve impulses travel throughout the human brain and nervous system. A nerve impulse is a wave of electrical activity that passes from one end of nerve cell to another. Each impulse is the same size it; it is the frequency, impulses per second, that carries information about the intensity of the nerve signal.
The nervous system is a network of cells called neurons which transmit information in the form of electrical signals.
yes the magenetic field is created because of that.
human electricity in the brain and nervous system creates human magnetic fields. There are billions of nerve impulses in the body and these are constantly creating complex human magnetic fields.
The human heart is a source of electro-magnetism that, even at a few meters away, is detectable by modern scientific instruments.
