Magnetic sail significant in the long term. In typical magnetic sail designs, the magnetic field is generated by a loop of superconducting wire. Because loops of current-carrying conductors tend to be forced outwards towards a circular shape by their own magnetic field, the sail could be deployed simply by unspooling the conductor and applying a current through it. The solar wind is a continuous stream of plasma that flows outwards from the Sun: near the Earth's orbit, it contains several million protons and electrons per cubic meter and flows at . The magnetic sail introduces a magnetic field into this plasma flow
Sun Stream the Rowley Mile to the adjoining July course. Ridden by Wragg, she won by three lengths from Blue Smoke, with Mrs Feather a further two lengths back in third. Sun Stream's success gave Lord Derby a seventh win in the race as both owner and breeder, and was very popular with the unusually large crowd. A month later, Sun Stream returned to the July course on 8 June for the Oaks Stakes. Although the race was not run at Epsom Downs Racecourse it was given its traditional name: wartime runnings at Newmarket had been known as the "New Oaks". The
