Exploring the history of African-American women's basketball will provide us with a more complete picture of urban black communities during the 1920s, '30s and '40s. I also see my work as an attempt to confer on some black athletes, belatedly, the recognition they failed to receive in their own time, when basketball, like most other sports, was almost completely segregated. These same magnets demonstrated to us the power and mystery of magnetic fields. Magnets and magnetic fields are now an integral part of our daily lives. A papers on the refrigerator.
Computers use magnetism to store information on the hard drive.
In our childhood bar magnets, all the microscopic irons are aligned in the same direction. This gives the toy magnet an external magnetic field that allows us to pick up nails. In fact, at room temperature FeTAC will have no external magnetic field. One of the properties that makes FeTAC special is that the magnetism occurs only in one-dimension. Unlike the toy bar magnet, where all the iron atoms are aligned with each other in three-dimensions, FeTAC only has a magnetic interaction in one direction.
