Unformatted text preview: k y in an equilibrium with a current J z ( x ) that consists of a pedestal of half width L , i.e. , the current is constant in the region  x  < L and zero elsewhere and produces a magnetic ﬁeld B y = B x/L for  x  < L , B y = B for x > L and B y =B for x <L . Plot Δ versus k y L . Calculate the marginal stability point. Calculate analytically an expression for Δ in the limit of k y L small....
