Magnetic water treatment is a technology that uses magnets to alter the structure of water without changing its chemistry. It works by applying a magnetic field to water, which exerts a Lorentz force on ions and increases collisions between ions. This causes water molecules to cluster into smaller, more "bio-friendly" formations that can prevent scale buildup and increase nutrient absorption in plants. Studies have shown magnetic water treatment can increase crop yields by 10-30%, reduce water and fertilizer use, and improve soil health. Case studies on wheat, peas, and amaranth found magnetized irrigation water significantly increased plant growth rates and nutrient content compared to non-magnetized water.

3. Definition
“Magnetic water treatment
does not change the chemistry of the
water but It alters the structure and
property of liquid water”

4. Principle
“Magneto hydrodynamics”
O Lorentz force is exerted on water ions
O The redirection of the particles increases the
frequency of collisions between ions of opposite
sides
O Combining to form a mineral precipitate or
insoluble compound

5. Magnetic water treatment
technology
O A water molecule consists of one oxygen and two
hydrogen atoms
O They form clusters with other water molecules
O Clusters come in many sizes depends on water
molecules involved

6. Cont.….
O Restructures the water molecules into very
small water molecule clusters,
O Each made up of six symmetrically organized
molecules.
O Cluster is recognized by the cell as "bio-
friendly"

8. Devices
O Two magnetic rods symmetrically oriented along
the axis of feed pipe
O Pole pieces at the end of each permanent magnet
focused the magnetic field
O Magnetic induction in the range of 3.5–136mT

9. Cont…
O Water flow direction should be from North
magnetic pole to South magnetic pole
O The magnets should be installed on the pipe
between the main valve and the irrigation pipe.
O The mounting plate serves to increase the
magnetic field present inside the pipe

10. Types
O Temporary magnets
O Permanent magnets
Interior installed magnet
Exterior installed magnet

12. How does it works?
O Water passes through the magnetic field, all
super- molecules vibrate
O This will intensify the internal vibration of
these super-molecules to the breaking point.

13. Cont.…
O These super-molecules fracture and release
their encaged particles (Ca,Mg).
O Precipitates come out of solution as a sludge
and can be easily removed from the system

O Extent shelf life of produce
O Increase seed germination

27. Cont.…
O Reduce water use up to 30%
O increase the levels of CO2 and H+ in soil
O Reduce total dissolved solids (TDS)
O Reduce fertilizer and pesticide needs
O Advanced ripening of fruits in all cases

28. Cont.…
O Affect soil nutrient availability
O Activate plant enzymes
O Reduce disease in livestock
O Reduce disease in aquaculture industry
O Increase the no of hydrogen bond
O Enrich soil permeability

32. Materials and methods
O Grains were selected and planted in twenty
pots
O Half of the pots were irrigated once a week
interval with tap water

water after magnetization
O Plant height, fresh and oven dry weight of
twenty wheat plants were determined

33. Results
O Growth criteria
O Photosynthetic pigment contents
O Indole and phenol contents
O Wheat yield and its components

37. Conclusion
O Results clear that all yield parameters
increased significantly by using magnetic
