What do u mean by magnetic field? The magnetic field is the area around a magnet in which there is magnetic force. Moving electric charges can make magnetic fields. Magnetic fields can usually be seen by magnetic flux lines.
At all times the direction of the magnetic field is shown by the direction of the magnetic flux lines. Does caffeine affect plant growth?
The effect of caffeine on plant growth is still a subject under study. Using grounded coffee in garden lawns is a common practice to make plants grow faster. However, coffee also contains other ingredients like potassium and phosphorous, which are known to enhance plant growth.
How do magnets work? Magnets are objects that produce magnetic fields and attract metals like iron, nickel and cobalt. The magnetic field's lines of force exit the magnet from its north pole and enter its south pole. Electromagnets produce magnetic fields only when electricity travels through their wire coils. How can we make magnetic water? In a small jar add in baby oil and iron oxide and mix together.
In a jar add in the mixture and fill with water. Wait for it to settle. Gravity pulls on the sprouting seeds from every angle as the device rotates, so the net effect is nearly zero. These earlier experiments were informative, but scientists can't be sure of their conclusions without running the experiment in the true weightlessness of Earth orbit.

The magnets should be strong — not those little do-dads you attach to the refrigerator, but a fairly powerful magnet such as that found in older speakers. Water should be directed at the base of the plant only, for the roots.
Root crops seem to fare better when the polarity of the magnets is reversed — the north pole facing the water stream. I have not yet tried this myself and what I am relaying is based on the word of others I believe reliable.
Allegedly magnetized water produces an increased yield and higher quality produce. Any wishing to study further on a scholarly basis are advised to see Possibility of Magnetotropisms existing in Plants.
