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 Stakes, Britain's most prestigious race for two-year-old fillies. In a closely contested three-way finish she was beaten into third place by Sweet Cygnet and Neola. She was regarded as one of the best juvenile fillies to race in Britain in 1944. Sun Stream began her three-year-old season in the seven furlong Upwell Stakes, a now discontinued race which served as a trial for the 1000 Guineas, in which she finished second to Exotic. Two weeks later, on VE Day, Sun Stream started 5/2 favourite for the 1000 Guineas which, because of the war, was moved from its traditional venue on
