I just heard about this a month ago and i'm about to preform a science project where i test my hypothesis of "if a plant is placed within a magnetic field then it will grow bigger and/or faster than a plant not in one." so i could really use this item. But i have no idea what it's called or where i can even get it. So if anybody could answer this, it would be a great help. Thank you

There are plenty of magnetic field strength sensors available. Probably the most sensitive is the SQUID, a superconducting quantum device. You won't need that sensitivity. Your harder tasks will be creating a field strong enough (and perhaps uniform) to make a difference, and designing a controlled environment so you can tell whether it makes a difference. You'll also need to do some research to see what has already been done in that area.

It was long long time ago an experiment on tomato glowing. By placing a powerful magnet either South or North pole at the bottom of tomato roots. Result finding the roots glow faster and bigger.

Magnet companies sell what is called 'magnetic viewing film' that would probably work for you, but it's not paper.
