how magnets affects plants growth?

Well, for one thing, the magnetic poles of the Earth are responsible for how much UV radiation reaches the ground.  So, the poles help regulate the amount and type of sunshine for a plant.  Another thing is that the the magnetic fields surrounding the planet affect the weather in a big way.  Weather affects plants.

its just a rumor. Magnetism does not induce cancer. We live in a polarised world with a magnetic north and south.

Some magnetic feild is what I beleive causes crop cricles...\nsince all electronics cease to function in and over crop circles

There really is not much good information about the effect of music on plants because all attempts to do controlled studies on plants and music result in "no difference". Any "differences" between a music treatment and a no-music control (or other-music treatment) in pseudoscience studies can almost always be attributed to some difference in other variables in the project which have not been suitably controlled (light, water, fertilizer, soil type, humidity, etc.)

Magnet therapy, or magnetic therapy, or magnotherapy is a pseudoscientific alternative medicine claiming that certain medical disorders can be effectively treated by exposure to magnetic fields. There is no scientific evidence for the claim but it may act as a placebo in some people. Adherents believe that magnetic fields from permanent magnets placed close to the body can cause bones to heal faster, relieve pain, and perform other forms of healing. It is most commonly used for joint disorders and back problems.\n\nProponents of magnet therapy claim that subjecting certain parts of the body to doses of magnetic "energy" (or fields) has a beneficial effect. This belief has led to the popularization of an industry involving the sale of magnetic-based products for "healing" purposes: magnetic bracelets and jewelry; magnetic straps for wrists, ankles, and the back; shoe insoles, mattresses, and magnetic blankets (blankets with magnets woven into the material); and even water that has been "magnetized"\n\nCriticism of these products focuses on scientific facts about magnets, including the claim that the typical magnet used in a bracelet purchased over-the-counter is not powerful enough to penetrate human skin, let alone strong enough to have a lasting effect on muscle tissue, bones, blood vessels, or organs. Notably, some people working in physics research work for hours per day with their whole body immersed in magnetic fields far stronger than those from the bracelets, and (if they observe precautions regarding pacemakers) are no more or less healthy than their peers. There are handheld neodymium magnets that produce a field of over one tesla and are often used in various hobbies. Household devices such as a garbage disposal, or an electric razor, also produce significant magnetic fields when in use.\n\nNo magnet healing product manufacturers have demonstrated scientifically that they actually achieve what they claim, and most cannot even agree on what exactly the magnetic fields do. Some claim that the magnets help to circulate the blood by some interaction with the iron in hemoglobin, a major component of red blood cells. However, in its ionised form, iron is not ferromagnetic. If it were, use of magnetic resonance imaging would instantaneously kill patients.[1] Still others claim that the magnets can restore the body's electromagnetic energy balance. There are also claims that the south pole of a magnet acts different on the body than the north pole. The list of ways that manufacturers purport that magnetic fields affect the body is almost endless.\n\nIt should be noted that many, if not most, of the websites that provide information and resources promoting the benefits of magnetic therapy belong to individuals and companies that profit from the sale of magnetic therapy products.

elements fall under one of three categories: stuff that is always attracted to a magnetic field, stuff that is always repelled by a magnetic field, and stuff that can be magnetized ei you can make a magnet out of it. For example, water (yes i know its not an element) is always repelled by a magnetic feild, titanium is always attracted and iron can be magnetized. To see the effects of water being repelled by a magnetic field, buy some neodymium magnets, (the bigget the better) and place it in a bowl of water so that the magnet is barely covered with water. place it in front of your compurer screen, and look at the reflection of the computer screen in the water just above the magnet. you will notice th reflection is warped just above the magnet.

A magnet whose magnetic properties is dependent on current flow.

Yes humidity does affect the growth of plants but the effect is greater in conditions of low humidity (dry).  When it is dry many plants will minimise opening of their stomata to reduce water loss this also has the effect of slowing gas exchange.  Plants need to take in CO2 for photosynthesis, if the stomata are closed this decreses the rate of photosynthesis and therefore the plant has less sugars created.  When the plant has less sugars (food) it can't grow as much.  \nSwamps can have the effect of flooding the root systems of plants so they don't work properly.  There are specially adapted plants that can survive in swamps, most can't.\nHope this helps

All of the above.\n\nActually even Magnetism is affected by heat.  Heat a magnet and it will lose its magnetism.\n\nChemical composition will also change.

Paramagnetism causes the substance to be attracted into the inducing magnetic field. It is associated with unpaired electrons.\n\nDiamagnetism causes the substance to be repelled from the inducing magnetic field. It is associated with paired electrons.

nitrogen for vegetative growth\nphosphorous for flowering and root growth\npotassium for seed and protection from pests and frosts\nmagnesium to a plant is like iron to people whereas we have iron as the central molecule of our blood plants have magnesium in their circulatory system..\n\nIf you look at the list of minerals and micronutrients on a potent multivitamin you will see a list of trace elements that are both considered essencial for humas but also for plants which like all of those in various amounts depending on type of plant and additionally they also like boron.\n\nOb1

Electromagnets are made out of metal that can easily be magnetized by applying DC voltage. Electromagnets do not occur naturally in nature but are manmade. Their magnetism can be turned on and off.\n\nPermanent magnets occur naturally in nature.

They get cold. \n\nThere are some effects on magnetic properties when you go very cold (search on magnetism AND temperature) especailly for electromagnets. Some things which aren't magnetic start to become so and things which are magnetic become more so. You wouldn`t notice much if you used a home freezer, you need to get much closer to absolute zero.    \n\nMaking it hot has a more important effect. A permanent magnet heated to above its Curie temperature will lose its properties.

A few magnets will do the trick.... even a really large scientific one.

Glad to see you're thinking, but this is an easily answered question.  \n\nTake for example a magnet.  Regardless of what is in front of your magnet it will still attract an object to a distance equal to its strength.\n\nex:\n\n.....(|)<<<< <[]<<<<<<<[]          \n\n......^..............^...... ......^\nMagnet......Metal..... ..Metal\n.................Object.... Object\n\nThe magnet is going to exert force on both of the objects without interference from first object.  \n\nBased on your definition of propagate...come to your own conclusion...that is the joy of thinking...we all have our own thoughts.

Anything where an electrical currant passes thru it,  also has an electromagnetic field, around it.\n Simple test- scatter iron fillings onto sheet of paper,place over circuit,motor,speaker etc, watch fillings change shape/format to that of electromagnetic field.
