Klein'sche Fields are an innovative magnetic field technology that does not require a power supply and is based on natural principles.
Klein'sche Fields are spatially structured, alternating polarity permanent magnetic fields. Blood, lymph, and other bodily fluids contain charged particles (ions) and are therefore electrically conductive. Laboratory experiments with flowing conductive fluids have shown that alternating polar permanent magnetic fields of the “Klein'sche Fields” type induce small electrical voltage differences. These observations are consistent with the known physical laws governing magnetic fields and moving charge carriers (Lorentz force, electromagnetic induction). These experiments provide physical evidence of how Klein'sche Fields behave with moving, conductive media.
For those interested, we provide background information on physical studies here: “The electrical effect of alternating polar permanent magnetic fields of the type Klein'sche Fields” (laboratory study by Dr. Petrow, Institute for Naturopathic Treatment).
Please note: These studies examine physical effects in model and laboratory environments. They do not constitute clinical proof of efficacy in the sense of promising a cure or relief for specific diseases.
Comparison: Electrically powered magnetic field systems & Klein’sche Fields
Magnetic field systems and Klein'sche Fields differ fundamentally in terms of their structure, handling, and technical implementation. Both concepts are based on magnetic principles, but are used in different forms. Electric magnetic field systems use mats, coils, or cuffs that are connected to a power source. Depending on the device, different electromagnetic field shapes are created, which are used for a defined period of time. While classic magnetic field systems work with electrically generated fields and are usually device-bound, Klein's fields do not require external energy sources and are permanently integrated into various product forms.
| Electrically powered magnetic field systems | Klein’sche Fields |
|---|---|
| Use with electricity or battery | Use without electricity or battery |
| Device-specific application | Product-integrated application |
| Time-limited use | Permanent use possible |
| Electromagnetic fields | Permanent magnetic, weak, inhomogeneous magnetic fields |
| Large-scale application | Targeted, local placement |
| Depending on the power connection | Location-independent and flexible |
About the inventor: Bernhard Klein

Bernhard Klein, born in Bremen in 1957, acquired his medical expertise through training with the German Armed Forces. From 1983 onwards, he devoted himself extensively to physical applications in the medical technology field.
As a certified medical device manufacturer, he developed an independent technological concept based on polymorphic magnetic structures without an electrical current – the so-called Klein’sche Fields. For many years, he explored magnetic principles and their technical implementation, sharing his knowledge through lectures in Europe and internationally.
Today, the portfolio includes various product solutions using Klein'sche Fields technology, which are handcrafted in Bremen. The aim is to develop high-quality, electricity-free products that impress with their material quality, workmanship, and everyday usability, and are designed for diverse living situations.
