Domino & N-1

Domino & N-1 – The Big Doctor & The Little Doctor

"These are your Big and Little Doctors — keep them at home and use them for whatever the body needs."
— Dr. Irma Sierra & Dr. Ralph U. Sierra

If there is one set of magnets every home should have, it is this one. The Domino & N-1 combination has been the foundation of the Sierra family’s biomagnetic practice for generations — recommended to patients, family members, and wellness seekers as the essential starting point for home biomagnetic therapy.

Together, they cover virtually any situation the body may encounter — from head to toe, surface to deep tissue, spot therapy to full-area coverage. No matter what your body needs, one of these two magnets is the answer.

Meet the Big Doctor – The N-1

The N-1 is a high-strength Grade 8 ceramic block magnet (approximately 3,850 gauss) measuring 6" x 2" x 0.5". Its large surface area and deep magnetic field penetration make it ideal for:

• Back, abdomen, thighs, and larger body areas
• Resting or sleeping therapy (placed under a pillow or mattress pad)
• Magnetizing large quantities of water
• Systemic and deep-tissue biomagnetic support

Meet the Little Doctor – The Domino

The Domino is a compact, portable ceramic magnet (approximately 3,500 gauss) shaped for precision spot therapy. It is ideal for:

• Targeted relief on wrists, knees, shoulders, and joints
• Headaches, neck tension, and localized discomfort
• Easy positioning with hypoallergenic tape or bandages
• On-the-go therapy — discreet and travel-friendly

Why You Need Both

The N-1 covers the big picture. The Domino handles the details. Together, they give you a complete home biomagnetic toolkit — versatile, powerful, and trusted by the Sierra family for decades. Both feature clearly marked Bio-North (negative, N) and Bio-South (positive, S) poles for proper therapeutic application.
