Text: Lake Superior (French: Lac Superieur; Ojibwe: -, Gitchi-Gami) is the largest of the Great Lakes of North America. The lake is shared by the Canadian province of Ontario to the north, the U.S. state of Minnesota to the west, and Wisconsin and the Upper Peninsula of Michigan to the south. It is generally considered the largest freshwater lake in the world by surface area. It is the world's third-largest freshwater lake by volume and the largest by volume in North America. The furthest north and west of the Great Lakes chain, Superior has the highest elevation of all five great lakes and drains into the St. Mary's River.

Text: The principal bridesmaid, if one is so designated, may be called the chief bridesmaid or maid of honor if she is unmarried, or the matron of honor if she is married. A junior bridesmaid is a girl who is clearly too young to be married, but who is included as an honorary bridesmaid. In the United States, typically only the maid/matron of honor and the best man are the official witnesses for the wedding license.

Question: is your maid of honor supposed to be married?

Text: An intuitive argument can also be used to show that the flux density outside the solenoid is actually zero. Magnetic field lines only exist as loops, they cannot diverge from or converge to a point like electric field lines can (see Gauss's law for magnetism). The magnetic field lines follow the longitudinal path of the solenoid inside, so they must go in the opposite direction outside of the solenoid so that the lines can form a loop. However, the volume outside the solenoid is much greater than the volume inside, so the density of magnetic field lines outside is greatly reduced. Now recall that the field outside is constant. In order for the total number of field lines to be conserved, the field outside must go to zero as the solenoid gets longer.

Question: is there a magnetic field outside a solenoid?
