US Scientists Develop an Innovative Magnet to Increase Efficiency of Nuclear Power Plants

Image
Scientists at the Department of Energy (DOE)  Princeton Plasma Physics Laboratory (PPPL) , in the U.S., have developed an innovative type of magnet that could facilitate the working of nuclear energy production devices such as tokamaks. It can also aid medical equipment such as MRI (magnetic resonance imaging) devices used to get detailed images of the human body. Image Credit: Pixabay What Are Tokamaks? A tokamak is a machine used to enclose plasma through doughnut shape magnetic fields called a torus. Plasma is a superheated matter that contains a large amount of charged particles such as ions, atomic nuclei and free electrons. It undergoes nuclear fusion to generate energy. Nuclear fusion is a reaction in which two or more atomic nuclei combine to form two or more subatomic particles (protons and neutrons) or atomic nuclei. Examples of plasma include natural phenomena such as lightning, aurorae, solar storm, star lightning. How do the Tokamak nuclear reactors work? In a tokamak, ele
