• By using identities first pointed out by Buckingham, it is possible to derive explicit and manifestly gauge invariant expressions for the linear magnetic response of a statistical system. If the approximation employed for the statistical operator fails to satisfy these identities, the lack of gauge invariance shows itself through the fact that different explicit expressions, which ought to give identical results, now yield a whole range of results depending on an arbitrary function α (q). However, it is possible to select the best function α (q) by a variational procedure. The form selected in this way is usually different from the prescription of calculating everything in London gauge, without making use of identities.
