Heinrich LenzBorn 24 Feb 1804; died 10 Feb 1865 at age 60.Heinrich Friedrich Emil Lenz was a Russian physicistwho devised Lenz's Law to describe the direction of flow of electric current generated by a wire moving through a magnetic field. Lenz worked on electrical conduction and electromagnetism. In 1833 he reported investigations into the way electrical resistance changes with temperature, showing that an increase in temperature increases the resistance (for a metal). He is best-known for Lenz's law, which he discovered in 1834 while investigating magnetic induction. It states that the current induced by a change flows so as to oppose the effect producing the change. Lenz's law is a consequence of the, more general, law of conservation of energy. |
MAGIC SQUARE: Calculate A-B*C
The aim is to place the some numbers from the list (5, 8, 10, 13, 16, 18, 37, 40, 43, 45, 67) into the empty squares and squares marked with A, B an C. Sum of each row and column should be equal. All the numbers of the magic square must be different. Find values for A, B, and C. Solution is A-B*C. The first user who solved this task is Nasrin 24 T.
