How and why does magnetism affect plant growth?

Question

I placed a large magnet in the pot of one of my plants & when I removed it to have a look, I found that the roots in that spot had grown towards the magnet instead of downwards as normal.!

kind of strange eh.?

It could have some use... but I don't know what for yet.??

ARTIFICIAL MAGNETIC FIELD EFFECT ON YIELD AND QUALITY OF TOMATOES

Authors:    V. Danilov, T. Bas, M. Eltez, A. Rizakulyeva

Abstract:

Seeds of two tomatoes (Lycopersicon esculentum. Mill.) varieties (cv. Rocco and Monza) were treated by passing them through an artificial magnetic field (MF) with a constant defined velocity before seeding. The seedlings obtained from MF treated and non MF-treated seeds were planted into the MF treated and non MF-treated plots. They were irrigated by MF-treated and non MF treated water.

Observations were made on early-yield, total-yield, begining of blooming, and quality of fruit. While significant differences were not observed in Rocco, important MF effects were clearly seen on Monza. Yield increases on Monza in magnet treated plots were around 28–51 percent, especially in early yields, and Monza bloomed three-four days earlier.
