Student A:Three discoveries challenged this foundation of magnetism, though. First, in 1819, Hans Christian Ørsted discovered that an electric current generates a magnetic field encircling it. Then in 1820, André-Marie Ampère showed that parallel wires having currents in the same direction attract one another. Finally, Jean-Baptiste Biot and Félix Savart discovered the Biot -- Savart law in 1820, which correctly predicts the magnetic field around any current-carrying wire.

Problem:The Cold wave of January 1977 produced the only known trace of snow in the greater Miami area of Florida ever reported (it snowed in the city of Miami). It occurred following the passage of a strong cold front, in combination with a high-pressure area situated over the Mississippi River Valley. As a result, cold air spewed across Florida, causing both snow flurries and record low temperatures. Most notably, the weather system brought snow flurries (seen in the air, but not on the ground) as far south as Homestead on January 19. No snow had ever been reported in south Florida before or since. Damage was most significant to agriculture, as major losses occurred to Citrus fruits and tender vegetables. Statewide, agricultural damage from the cold wave totaled to $350 million (1977 USD), and losses overall totaled to $2 billion (1977 USD). One fatality occurred due to an automobile accident in Central Florida, which was related to the cold wave.
