What is a toroidal field coil?
What is a toroidal field coil?
The toroidal field coils are the ITER magnets responsible for confining the plasma inside the vacuum vessel using high-performance, internally cooled superconductors called CICC (cable-in-conduit) conductors. Each coil is made up of a superconducting winding pack and surrounding stainless steel coil case.
What is a toroidal field?
toroidal field A magnetic field with no radial components, e.g. where the magnetic lines of force lie on an electrically conducting spherical surface such as the surface of the Earth’s core. Such a field is not detectable at the Earth’s surface, in contrast to a poloidal field.
What are the roles of toroidal and poloidal magnetic field on tokamak?
Confining the plasma Current tokamaks use two magnetic fields, a poloidal and a toroidal one. The poloidal field is created from the transformer effect and the current in the plasma itself. This spinning keeps the particles constantly moving toward the center of the toroidal field and away from the walls.
How strong are ITER magnets?
Its magnetic force is strong enough to lift an aircraft carrier 2 meters (6 feet) into the air. At its core, it will reach a magnetic field strength of 13 Tesla, about 280,000 times stronger than the earth’s magnetic field.
What are toroidal transformers used for?
Toroidal transformers are used in electronic applications that step up or down a voltage or for the isolation of electronic equipment from a source of voltage. Different transformers are used for different applications.
How much energy does the tokamak produce?
It is intended as a demonstration that a practical fusion reactor is possible, and will produce 500 megawatts of power.
What do toroids do?
The toroids are used to step down or step up a voltage. Circuits, such as power supplies, amplifiers, and inverters, use toroids. Additionally, electrical equipment, such as computers, televisions, audio systems, and radios, use toroid coils.
What are tokamaks used for?
tokamak, Device used in nuclear-fusion research for magnetic confinement of plasma. It consists of a complex system of magnetic fields that confine the plasma of reactive charged particles in a hollow, doughnut-shaped container.
How does fusion energy work?
In a fusion reaction, two light nuclei merge to form a single heavier nucleus. The process releases energy because the total mass of the resulting single nucleus is less than the mass of the two original nuclei. The leftover mass becomes energy. Fusion can involve many different elements in the periodic table.
What is the most powerful magnet on Earth?
The strongest permanent magnets in the world are neodymium (Nd) magnets, they are made from magnetic material made from an alloy of neodymium, iron and boron to form the Nd2Fe14B structure.
Where is the world’s strongest magnet?
The world’s most powerful magnet was built in the United States in 2011 in a University Center in Florida. This super magnet has a magnetic field of 44.14 Teslas, and we can say that it is 900 thousand times that of the earth and more than 9 times that of a closed resonance equipment that we find in a hospital.
What is the difference between toroidal transformer and normal transformer?
Comparing a Toroidal Transformer vs. Standard Transformer. A toroidal transformer is a special type of electrical transformer with a doughnut-like shape. Compared to a traditional laminated transformer, a toroidal transformer provides higher efficiency, a more compact size, and less audible vibrations and hum.
