Why are magnets used to confine plasmas in some fusion experiments?

Because the plasma is ionised it can be controlled by a magnetic field, and so confined in a toroidal chamber in which it can be heated to a very high temperature.

What does nuclear energy include?
Mostly power plants operating with fission reactors. Also experiments with nuclear fusion, and nuclear weapons
Why dont charged nuclei repel each other in a plasma?
They do. In those plasmas which don't fly apart there are other factors. In plasmas for fusion power, the plasmas are constrained by magnetic forces which keep the material in proximity. There is also the strong nuclear force. This is a very strong force, with a very short range. If two positively charged nuclei can be forced close enough together, then the strong nuclear force, which pulls them together, will become more powerful than the electromagnetic force, which pushes them apart. Then they form one nucleus, and spit out a lot of energy, and sometimes a neutron.
What is the element used in fusion?
Fusion experiments and designs for fusion reactors generally focus on hydrogen, in the forms of deuterium (hydrogen-2) and/or tritium (hydrogen-3). It should be born in mind that there is not much preventing any atom of any natural element undergoing fusion with something else. In fact, virtually all of what is around us is either hydrogen or something made by fusion, and this includes all the heavy elements like lead uranium.
What are some methods of containing plasma?
The plasma in a fluorescent light or plasma ball, is contained by glass. Fusion plasmas are too hot to contain in any "container", so it is contained by magnetic fields, The plasma in the sun is partly contained by gravity, though a proportion of it is lost as the Solar Wind.
Does fusion occur only under extremely high temperatures?
Nuclear fusion of light elements is the process operating in the stars to produce energy, and needs very high temperature to occur. Experiments on earth to aim at producing useful power from fusion have been progressing for many years. The reactants most likely to be used are isotopes of hydrogen, deuterium and tritium. These need to be heated to some hundreds of millions of degrees kelvin before reaction starts. Fusion reactions have been seen, but only for less than 1 second so far. Fusion is not a chemical reaction, it is a nuclear process.
What has the author Timo Pattikangas written?
Timo Pattikangas has written: 'Studies on the parametric decay of waves in fusion plasmas'
What is nuclear fusion used for?
Up to now only in H-bombs. Experiments in fusion are on going though.
What substances does nuclear fusion use?
Experiments in fusion have used deuterium and tritium, both isotopes of hydrogen
What are some examples of plasma?
an exaple of plasmas is...sun,nueclier fusion,or a spark -Ciara

Nuclear fusion opperratin?
Nuclear fusion on earth has not been achieved in any way that could produce power, but experiments continue.

Can you use nuclear fusion on Earth?
It may be possible, experiments continue but success is a long way off.
What do you use Nuclear Fusion for?
At present it is only used for experiments, to try to develop a reliable power source
Is Fusion a process in which existing nuclei combine to make new nuclei?
Yes. In nuclear fusion, experiments are trying to produce fusion of nuclei of deuterium and tritium, which are isotopes of hydrogen. The product will be nuclei of helium plus released energy.
