The grain food group is the orange part of the new MyPlate and the Food Pyramid. Our printables feature fun worksheets, activity sheets and coloring pages to help children learn about the foods that belong to this food group and how it helps their body.
A magnet keeper, or armature is a ferromagnetic bar made from soft iron or steel which is placed across the poles of a permanent magnet to help preserve the strength of the magnet by completing the magnetic circuit; it is particularly useful for magnets which have a low magnetic coercivity, such as Alnico magnets. magnet keeper, or armature is a ferromagnetic bar made from soft iron or steel which is placed across the poles of a permanent magnet to help preserve the strength of the magnet by completing the magnetic circuit; it is particularly useful for magnets which have a low magnetic coercivity, such as Alnico magnets.
The magnet is like a tunnel, open at both ends, allowing light and air inside. If you are large or have a fear of enclosed spaces (claustrophobia), please tell your doctor in advance so arrangements can be made. The technologist will help you onto a scanning bed. You will lie flat on the bed. The scanning bed will move into the center of the magnet.
