How strong are Neodymium (Rare-Earth) Magnets?

2.7x stronger than normal ferrite magnets. Rare, light and permanent. Discover the power of Neodymium (rare Earth) magnets for precise door movement and completely silent door close.

In the world of architectural design and hardware, innovation often comes from unexpected sources. Neodymium magnets, with their exceptional strength and versatile magnetic properties, have emerged as game-changers in various applications. One such arena where neodymium magnets are making a significant impact is in magnetic door closers and door catchers. These unassuming yet powerful magnets are revolutionizing the way doors are closed, latched, and secured, adding both functional efficiency and aesthetic appeal to buildings and spaces

What are Neodymium Magnets?

Neodymium magnets are rare earth magnets made primarily from an alloy of neodymium, iron and boron and can be sometimes reffered to as Neo Magnets and boasts an astonishingly high magnetic energy and magnetic flux density. Their small size belies their immense strength. Neodymium magnets are capable of producing magnetic fields several times more powerful than traditional magnets, making them an attractive choice for a wide range of applications, including architectural hardware at Two Tease Architectural Hardware. 

Where are neodymium magnets used?

The Power of Neodymium Magnets in Magnetic Door Closers
Magnetic door closers are an integral part of commercial and residential spaces. These devices provide a controlled and gentle way of closing doors, preventing abrupt slamming and wear on the door and frame. Traditional door closers often rely on hydraulic mechanisms, which can be bulky and require frequent maintenance. Neodymium magnets offer a compelling alternative.

At Two Tease Architectural Hardware, neodymium is used in mulitple ARGENTA  products.

ARGENTA  MAGNOTICA PRO E & MAGNOTICA PRO SEa magnetic contactless door catch. Ideal for use with pivot hinges (Pivotica Pro) and holds interior doors shut without the need for a door handle or latch.  It can be installed on any  wooden door and frame.This magnetic closure is a perfect solution for many applications including holding pivot door in the hold close position, pantry doors, walk in closets or any commercial interior or residential interior door.

The concealed pivot hinges, PIVOTICA PRO 100 E. Implemented in the pivot head to make the installation process faster and easier. Magnetic strength can be adjusted.


Are Neodymium Magnets permanent? 

Neodymium magnets are the strongest permanent magnets commercially available that is utilised in  an endless arrray of applications. They have high coercity (resistance to de-magnetisation)  and have the ability to maintain their maximum magnetisation strength for long periods of time.  As a result, they are a highly sought after magnet where permamence is incredibly important.

Benefits of neodymium magnets in hardware

1. Secure and Invisible Latching
Neodymium magnets are exceptionally strong for their size, allowing doors to be securely held in place without the need for traditional mechanical latches or protruding hardware. This invisible latching mechanism contributes to a clean and minimalist aesthetic that is becoming increasingly popular in modern architecture.

2. Adaptive Solutions
Neodymium magnets offer a dynamic approach to door catchers. They can be integrated into doors of varying thicknesses and materials, adapting seamlessly to the design while ensuring a secure hold. This adaptability is a boon for architects and designers who seek solutions that blend effortlessly with their overall vision.

3. Touch of elegance:
Beyond their functional benefits, neodymium magnets add a touch of elegance to door catchers. Their discreet presence maintains the visual coherence of a space without compromising on safety or utility. This makes them particularly suitable for projects that prioritize aesthetic sophistication.

Are Neodymium Magnets safe?

Due to their strong magnetic force, neodymium magnets can attract to each other or to ferromagnetic surfaces with significant force. Take care during installation because pinching of the skin can occur.

Remember that magnetics are used in day-t0-day objects such as our mobile phones, fridges, wireless earphones, TV’s and headpones.
