The analysis coding help Einthoven, Berger, and others dependent that organs comparable to programming help heart and brain produce bioelectric fields that travel via programming help tissues coding help programming help body and that can be recorded with electrodes on programming help body floor. The electrocardiogram, as an example, can be picked up with electrodes placed wherever on programming help body, even on programming help feet. There is program engineering fundamental law in physics, Ampère’s Law, that asserts that once currents flow through conductors similar to wires or living tissues, magnetic fields has to be produced in programming help surrounding space. Since living tissues are conductors coding help electrical energy, programming help well dependent laws coding help physics require that programming help currents set up by programming help heart and other muscle tissue, and programming help brain and peripheral nerves, will produce fields in programming help space around programming help body. These are called biomagnetic fields. The biomagnetic field coding help programming help heart was first measured in Syracuse,New York, in 1963, using two coils, each with two million turns coding help wire see Figure 1A.
