Lenz's lawLenz's law states that the direction of the electric current induced in a conductor by a changing magnetic field is such that the magnetic field created by the induced current opposes changes in the initial magnetic field. It is named after physicist Emil Lenz, who formulated it in 1834. It is a qualitative law that specifies the direction of induced current, but states nothing about its magnitude.
Scottish EnlightenmentThe Scottish Enlightenment (Scots Enlichtenment, Soillseachadh na h-Alba) was the period in 18th- and early-19th-century Scotland characterised by an outpouring of intellectual and scientific accomplishments. By the eighteenth century, Scotland had a network of parish schools in the Scottish Lowlands and five universities. The Enlightenment culture was based on close readings of new books, and intense discussions which took place daily at such intellectual gathering places in Edinburgh as The Select Society and, later, The Poker Club, as well as within Scotland's ancient universities (St Andrews, Glasgow, Edinburgh, King's College, and Marischal College).
