BioFlex™ Concentric Field Magnets — Evolved for Modern Clinical Use

From flexible wellness pads to rare-earth precision

For years, BioFlex flexible rubber magnets introduced thousands to the concept of alternating concentric magnetic fields. These original designs used flexible rubber magnets, not unlike the common fridge magnet material, to create circular zones of alternating north-south polarity — a concept that helped shape the early science of static magnetic field therapy.

While the original BioFlex magnets were gentle and flexible, they had two main limitations: low magnetic strength and limited field depth.
The new Q Magnets BioFlex CF-series overcomes both by replacing the ferrite composite with solid rare-earth Neodymium cores and integrating a stainless-steel flux plate to direct the field toward the body.

The Next Generation: CF-Series Neodymium BioFlex Magnets

	CF28-3 Concentric Field Magnet  28 mm × 3 mm, 42 mm (1.5″) penetration
	CF50-3 Concentric Field Magnet 50 mm × 3 mm, 48 mm (1.9″) penetration

Both models preserve the original BioFlex concept of alternating concentric rings while producing a field up to eight times stronger and three times deeper, ideal for abdominal, lower back, knee, pelvic, or deep musculoskeletal applications.

Scientific Validation of Concentric Field Designs

1. Mayrovitz et al. (2021) — Nova Southeastern University

Effects of a Concentric Rare-Earth Magnet on Menstrual Cycle Pain (Cureus 13(1): e12801)

A double-blind, randomized, controlled trial tested a 0.4 Tesla concentric neodymium magnet on women suffering menstrual pain.

• N = 36 participants (18–35 yrs)
• Average pain reduction: 41.8 % ± 31 % (active) vs 20.8 % ± 16 % (sham), p < 0.05
• 58 % of magnet users achieved ≥ 35 % meaningful relief versus 18 % of controls
• No adverse events

“Results suggest that short-term wearing of the magnet produces meaningful pain reduction in some women.”
— Mayrovitz H et al., Cureus 2021

This was the first clinical validation of concentric rare-earth static magnets, confirming that balanced multipolar fields can meaningfully reduce pain within minutes of wear.

2. Vallbona et al. (1997) — Baylor College of Medicine

Response of Pain to Static Magnetic Fields in Post-Polio Patients (Archives of Physical Medicine & Rehabilitation, 78: 1200-1203)

The first randomized, double-blind, placebo-controlled trial on static magnetic fields for chronic pain — led by Dr. Carlos Vallbona, a respected physician and researcher who initially sought to disprove magnet therapy.
Instead, his study found:

• 76 % of magnet-treated patients reported pain relief vs 19 % in the placebo group
• Pain reduction occurred within 45 minutes and lasted for days
• No side effects were observed

These surprising results, published by a mainstream medical team at Baylor, sparked global interest and earned coverage in the New York Times.

3. New York Times Coverage (1997)

The New York Times article “A Tiny Magnet for Pain Gets Respect” highlighted how Dr. Vallbona’s skepticism turned into cautious optimism after observing clear, measurable benefits in his patients.

As the article noted:
“Dr. Vallbona expected to prove magnets useless. Instead, his patients’ pain diminished — and so did his doubts.”

The article underscored that magnetic field therapy had moved from curiosity to legitimate scientific investigation, laying the groundwork for decades of follow-up research.

Applications of the CF-Series

The new neodymium BioFlex magnets are suited for:

• Pelvic or menstrual pain (dysmenorrhea)
• Chronic pelvic and abdominal discomfort
• Lower-back, hip or sacroiliac pain
• Visceral referral pain where deep uniform penetration is required

They may be combined with other Q Magnets (quadrupolar or hexapolar) for layered treatment protocols when both deep field penetration and high spatial gradients are beneficial.

Safe, Durable and Australian-Made

• Australian Made & ARTG Listed (ARTG 132324)
• No batteries, heat or moving parts
• Biocompatible sealed housing with stainless flux plate
• Reusable and long-lasting; field strength remains stable for decades
• Not suitable for those with implanted pacemakers or ferromagnetic devices

The new BioFlex CF-series represents the culmination of 25 years of magnetic field research — from Dr. Vallbona’s groundbreaking 1997 Baylor trial to the recent Mayrovitz 2021 concentric neodymium study.

By uniting classic alternating-ring geometry with rare-earth precision, Q Magnets delivers a deeper-penetrating, clinically validated static field therapy tool suitable for both home and professional use.
