A tokamak is a type of magnetic confinement device used to create controlled nuclear fusion reactions. It uses magnetic fields to confine a hot plasma of hydrogen isotopes, forcing them to collide and fuse together, releasing energy in the process. The goal is to achieve sustained fusion reactions that could potentially provide a clean and abundant source of energy in the future.

What limits scientists from downsizing the tokamak reactor?
Scientists are limited in downsizing tokamak reactors due to the need for a certain magnetic field strength to confine the plasma, control instabilities, and sustain fusion reactions. Additionally, scaling down the size of the reactor can lead to challenges in maintaining high plasma temperatures and controlling heat and particle loads on the materials. Researchers are actively exploring new designs and technologies to overcome these limitations for potential future reactors.
Where does Fusion reactions occur in what?
Fusion reactions occur in the core of stars, including our Sun. These reactions involve the fusion of light atomic nuclei to form heavier elements, releasing large amounts of energy in the process.
How is electromagnetism used in containing nuclear fusion reactions?
Electromagnetism is used in containing nuclear fusion reactions by creating strong magnetic fields that confine and control the hot plasma of hydrogen isotopes. These magnetic fields prevent the plasma from touching the walls of the fusion chamber, maintaining its stability and allowing the fusion reaction to occur under controlled conditions. The electromagnetic confinement helps to achieve the high temperatures and pressures required for nuclear fusion to take place.
I am what is being investigated to contain fusion reaction?
You are most likely referring to a magnetic confinement fusion device, such as a tokamak or a stellarator. These devices use powerful magnetic fields to confine and control high-temperature plasma, enabling the conditions necessary for a controlled fusion reaction to occur. Scientists and researchers study and investigate these devices in order to develop a viable and sustainable method of achieving nuclear fusion as a clean and abundant source of energy.
What conditions common to most stars including our sun appear to be necessary in order for fusion reactions to take place?
Nuclear fusion requires an environment of extreme energy, or, said another way, extreme heat. Temperatures are so high that any matter there exists as plasma. In addition to the extreme heat, stars use extreme gravity to compress the plasma to facilitate continuous fusion. In our attempts to duplicate this process, we have to contain the plasma, and the best we can do is some kind of magnetic cage like the tokamak.

What is the toroidal chamber used to produce fusion reactions in heated plasma?
tokamak
What was the name of the first nuclear fusion reactor?
You think probable to Russian installation Tokamak.
What is the role of tokamak machine in plasma physics?
A tokamak is a device used to confine high-temperature plasma for the purpose of studying nuclear fusion. It creates a magnetic field that confines the plasma in a toroidal shape, allowing for controlled fusion reactions to occur. Tokamaks are essential in advancing our understanding of plasma physics and developing fusion energy as a sustainable power source.
Who invented the Tokamak?
The concept of the tokamak was developed by Soviet physicists Igor Tamm and Andrei Sakharov in the 1950s. However, the first operational tokamak was built in the Soviet Union in 1958 by Oleg Lavrentiev.
What do scientist hope to achieve with the research on the Tokamak Fusion Reactor?
Scientists hope to achieve a sustainable and controllable fusion reaction that can generate abundant clean energy. The research on Tokamak Fusion Reactors aims to overcome the technical challenges of achieving self-sustaining fusion reactions and commercialize fusion power as a viable alternative energy source. Success in this research could help address global energy needs and reduce dependence on fossil fuels.

Which one of the following countries has currently largest tokamak type reactor and created first plasma?
You don't give the list of 'following countries' ! However I believe the largest or most powerful tokamak so far is the JET at Culham in England. See link below. The new one in S Korea looks perhaps to surpass that but it has not yet been fully operated. The tokamak originated in Russia, it was a brilliant development which took western science by surprise, but is now pretty universal in fusion research. The other possible lead is by laser ignition which is being promoted in a few places, but is very difficult to set up accurately. There is a Wikipedia article on 'tokamak' which gives a long list of facilities in many countries.
How is plasma confined in a tokamak?
Plasma in a tokamak is confined using magnetic fields to keep it away from the walls of the chamber. The magnetic fields create a torus-shaped confinement area where the plasma can circulate without touching the walls. This confinement allows the plasma to reach the high temperatures and pressures needed for nuclear fusion reactions.
