SMALL HYDROMAGNETIC OSCILLATIONS OF A TWO-DIMENSIONAL CAVITY,
Abstract
Two models are formulated. In the first, the cavity surrounds a finite number of line currents immersed in a fluid of infinite electrical conductivity. The fluid is free of magnetic field, and is at uniform pressure. The cavity in the second model is due to a finite number of line currents inside the cavity, and a uniform magnetic field outside. Material of infinite conductivity is trapped between the internal and external magnetic fields. Integral expressions for the magnetic potential energy are found when the system is subjected to a small general displacement. For the physical models formulated, the kinetic energy may be found, and Lagrange's equations can then be used to find the normal modes of oscillation. (Author)
