Two Bars
Two bars of iron lie on a table. They look identical, but one of them is magnetized [with a pole at each end], and the other is not. How can you discover which bar is magnetized if you are only allowed to shift them on the table, without raising them and without the help of any other object or instrument?
Answer:
Take either bar and push one end against the middle of the other bar, forming a T. If the magnetized bar is the top of the T, there is no pull on the other bar.
