摘要:
A comparison is made here between the magnetic field and electric potential produced by a thin strip of frog heart muscle. An experimental test is made of the theory which states that the wave front of a single fiber (or parallel bundle of fibers as in this strip) can be represented, for both the magnetic field and electric potential, by the same single‐current dipole. First, an experimental measurement is made of the ratio of magnetic field/electric potential produced by an actual current dipole in an electrolytic tank. Then the dipole is replaced by the muscle strip and a measurement is again made of the ratio; this is done for three muscle strips at eight different source‐to‐detector distances ranging from 1 to 5 cm. It is found, in all cases, that the muscle ratios are equal to those of the actual dipole to within the experimental uncertainty of ±10%. Therefore, to this extent the theory is verified for this case of a thin strip of frog heart tissue.
