Air France has said that Flight AF 447 sent an automatic signal indicating electrical problems while going through strong turbulence early in its 11-hour flight from Rio de Janeiro to Charles de Gaulle airport in Paris.
Since nerve cells use electrical signals, and magnetic fields can induce and disrupt such signals, a strong, well-aimed magnetic stimulation can affect the brain's operation.
Those electrical properties are truly exciting, and something that can be turned into a film which is both strong and thin has a lot of potential applications.
