This is the biggest magnetiser we designed.  It contain powerful neodymium magnets,
People use these on shower heads, wine bottle filling etc.
How magnetiser works.
It makes medium as liquid  or gas thinner (lower viscosity).
Molecules of madium are grouped, looks like  balls.
Magnetic lines make molecules  aligned along them. By any movement lines of molecules break, so most of them float as single molecules not groups.
Magnetized water go through membrane faster in reverse osmosis.
Magnet put on live organism makes blood thinner ,has healing properties (N-side).
We carry diffent neodymium magnets.
Hole is 27 mm.
We put new, lower price.
