The motion in the liquid core of the earth due to the bodily tide can induce a periodic magnetic field having the frequency sigma of the tide as well as multiple frequencies, including a steady term. The coupling coefficient for the steady term between the convectively inducing and induced fields is estimated to be of the order of sigmaH(2)/lambda, where H denotes the height of the equilibrium tide, and lambda = 1/4pikappa, kappa denoting the electrical conductivity of the core. With sigma = 1… CONTINUE READING
