... quantity p + B 2 / 2 µ0 is the total pressure. The second contribution is called the magnetic pressure; the magnetic field resists compression, just like the fluid pressure. The tensor BB / µ0 is called the hoop stress. We will see that it resists shearing motions. The total energy is the sum of the ...
