Comparing the Parapulser® base unit with the strongest pulser
so far, the SOTA Instruments magnetic pulser SOTA MP5,
reveals the following differences:
Pulse frequency: 2.00 Hz / 0.2315 Hz = PP is 8.64 times
Mag flux density: 0.664 T / 0.632 T = PP is 1.05 times
Pulse raise: 469 ms / 953 ms = PP is 2.03 x faster
Pulse fall: 512 ms / 4532 ms = PP is 8.85 times faster
Pulse steepness overall difference: 2.03 + 8.85 = PP is 10.88
The Parapulser ® base unit contains, in its 2 Hz basic license a
5-10fold induction performance, compared to the SOTA
Instruments Magnetic Pulser MP5. Accordingly, the Pro
License with 20 Hz provides an approximately 80fold induction
performance. Precise measurements (at different distances from the coil) are to be
published shortly (summer 2012).

* Magnetic induction is the generation of an electric current in a conductive medium, resulting from the fact
that a changing magnetic field moves electrically charged particles (electrons / ions) (= law of induction). A
current generated in this way is called therefore "induced current". With the help of induction currents,
certain effects can be exerted on the tissue and the body cells. The induction capacity i.e., the amount of
energy that can be generated per time unit is directly dependent on the pulse frequency (in Hz), the rate of
change of magnetic flux density (dT / dt), and the duration of the magnetic field change (in milliseconds).
**) The measured values on the oscilloscope differ from the induction effective rise and fall times, which are
measured from 0 to max. In metrology, these times are only measured in the window of 10 - 90% of the
amplitude, in order to compare them meaningfully.
For the application to the body, the following factors are crucial:
a) A rapid change of the magnetic field, i.e., possibly rapid build-up and desctruction of the magnetic field,
because the greater is the induced current in the body and thus its effectiveness.
b) A high maximum flux density, because this is decisive for the depth of the magnetic pulse. The magnetic
field decreases with the cube of the distance!
Treatment with a commercially available magnetic pulser was characterized by extremely long waiting times
(= capacitor-charging time of 2-5 seconds between pulses). The Parapulser heralds a new age: The
induction, which the SOTA MPG5 delivers in 20 minutes (1200 seconds) with 350 pulses, is reached by the
Parapulser® at its maximum level in just 15 seconds. Other way, the comparison is even more drastic: For
the induction, which the Parapulser® builds up in just 5 minutes within the body, the MPG5 would need a
treatment period of 350 minutes or 5.8 hours. If you add a cooling-down period of 5 minutes per 20 minutes
pulse operation, that would add another 1.5 hrs to the overall continuous use of the MPG5.
The Parapulser® provides already in the 2 Hz basic version an approximately eightfold higher induction
capacity than the SOTA MPG5 magnetic pulser, but it costs only around 20% more.
Tesla/Frequency comparison of magnetic pulsers:
Above image shows magnetic flux vs. frequency comparison. The Parapulser® covers a wide range from 1-
20 Hz, the SOTA MPG5 and the German “Blue Power Puls 2” both remain in the Sub-Hertz category.
Above diagram displays the number of pulses until overheating break. Again, the Parapulser® leads with
well over 10,000 pulses in the 2 Hz (8 fold speed compared to SOTA MPG5) and with up to 6000 pulses in
the 20 Hz mode, whereas both the SOTA MPG5 and the “Blue Power Puls 2” are struggling hard to reach
anywhere close to 300 pulses, before the obligatory heat sensor releases its interruption signal (it may
takes well over 20 minutes to cool down again).
Parapulser: Pulse steepness comparison
The chart above shows the pulse curves. While Parapulser and SOTA come close to each other, the pulse
curves of Blue Power Pulse II and the Australian Super Magnetic Pulser remain far behind. However, the
strength (in Tesla) is essential for the penetration depth, as this decreases with the cube of the distance
Parapulser: Induction performance comparison
World’s first: The induction performance (voltage increase per second) of a pulser, measured directly on its
coil surface, was determined and compared with other pulsers for the first time. The superiority of the
Parapulser by orders of magnitude is already evident in all clarity. At large distances (> 1 cm), it would even
yield much stronger, due to the exponential decay of the magnetic field. Through the clear code (V / s), for
the first time, an objective comparison between all types of magnetic pulsers became possible, without
having to know a device’s parameters in detail.
In the diagram you can see that the Super Magnetic Pulser leaves the other two sub-Hertz pulsers far
behind, but it ends, where the Parapulser starts. Moreover, the considerable heat development of the Super
Magnetic Pulser at the highest pulse speed, limits its performance significantly.
Parapulser: Measurement circuit for induction performance
The measurement circuit for the above induction comparison is not trivial, but can be replicated relatively
easily with help of the circuit plan. Thus, also competing manufacturers can reconstruct the readings at any
