The transient plane disturbance of a stream at any angle to the applied magnetic field is studied. For an airfoil, when this angle is comparable to the thickness ratio, the potential disturbance is not comparably small. Such a result persists for non‐vanishing Alfvén numbers, so that the method developed for aligned fields will not succeed. Care is taken to show that the Alfvén waves emitted by a body are not capable of realigning the flow into the direction of the magnetic field, which would be the only way of avoiding the airfoil conclusion.
