The human body does not have a dipole field like the earth or a metallic magnet. However, the human body does send out very weak EM signals and it also responds to signals. The emerging EM therapy field shows that there is potential to accelerate healing with EM energy.
The original research regarding healing showed that human bones are piezoelectric, and the EM signals emitted are amplified/caused by shock (such as high impact exercise). Feeding carefully tuned EM energy into the body simulates this shock, and you get the benefits without the strain.
This research resulted in machines that oscillate in the ultrasonic range to stimulate bones. These machines were proven to help slow and even reverse the effects of osteoporosis. Further research showed that a static EM field can stimulate the bones into "filtering" the EM energy into the person's natural resonance. Reading and replicating that resonance in addition to the static field showed additional positive effects. Ions bond to proteins and enzymes and catalyze the entire biological process.
Passive EM emitted by the nervous system is pretty much under-researched, but some argue that the signals produced by the human nervous system can be detected from as little as twelve inches, or as far as five to eight feet.

No, but we do emit a magnetic field. This is because our nervous system carries currents throughout our bodies, and we know from Maxwell's equations that magnetic fields are created from moving charges; which is exactly what a current is.
yes obsolutely.Humans have electic field around them which is knowns as HEF humen electric field.
Yes,I think we breath it out and plants get it and they give us oxegen which we breath and than emit carbon dioxide
Butterflies do not emit unpleasant odors, but some caterpillars do. Swallowtail caterpillars are known for emitting an unpleasant odor to offend wasps and bees.
This is called internal fertilization. It happens in birds and mammals, whereas amphibians emit eggs and sperm to meet in the outside world.
No, but certain mosses and fungi can emit a low, steady light through bioluminescence. Under certain conditions, trees can gain a bluish glow from St. Elmo's Fire.
According to other Wikipedia answers, breathing by humans produces approximately 2.3 pounds (1 kg) of carbon dioxide per day per person.If there are approximately 6.8 billion humans on the earth, collectively they would emit 6.8 billion kg per day, or 6.8 million metric tons per day. In a 365 day year, humans would produce 2.482 billion tons from breathing.The Energy Information Administration of the US government said in their May 27, 2009 International Energy Outlook 2009 that world carbon dioxide emissions were 29.0 billion metric tons in 2006.Human breathing would then be contributing approximately 8.5% of all CO2 emissions.It is important to remember that breathing is carbon-neutral, that is, we take in carbon when we eat and drink, and this same carbon is emitted when we breathe. So breathing does not add extra carbon dioxide to the atmosphere.
Hot objects emit infra-red radiation. E.g. the human body.
Yes. The electric motor does emit some heat. Also, when the car is stopping, forward energy is converted into heat.
yes they are not to the touch but they run like a battery they can emit an electric charge and deliver it to its predator or prey.
Electric and Magnetic Charges.
All elements emit colors when an electric current is applied.
The Wienβs law for maximum intensity is, Here, is the wavelength of maximum intensity and T is the temperature of human body. Rearrange the above expression for . Substitute for T to find . So the maximum energy is radiated at 9355.83nmK. Humans emit infrared off radiation which is electromagnetic radiation with a frequency lower than visible light.
Yes. When a charged particle such as an electron vibrates, it emits both an electric field and a magnetic field in a wavelike pattern. This electromagnetic wave is the same as a light wave, and if the charged particle is vibrating at the right frequency, it will emit visible light.
No, electric cars don't emit carbon dioxide but some electricity comes from fossil fuels which releases carbon dioxide. Although electrics are don't emit pollution, there are still some drawbacks. Electric cars are inefficient, they can only power up to a certain speed and the fuel needs to be filled up often.
I am not sure what you mean by collecting gravity. It might be useful to consider an electric field in comparison: You can collect charges, but you cannot collect the field itself. A field will follow the charges around however. In the same way you can collect massive objects (or rather objects with energy), but you cannot collect the gravitational field they 'emit' itself.
Heat.
anything hotter than absolute zero temperature
were gonna die in 2012
