Comprising a primary coil of insulated copper wire wound on a cylinder and fitted with terminals, together with a secondary coil of fine insulated copper wire wound on a cylinder into which the primary coil may be fitted. A soft iron core, for inserting in the primary coil, is included. To demonstrate the concept of induced current and with the soft iron core the electromagnetic effect can also be demonstrated.

Ask your class to identify each of 12 different samples by determining their density. Each cylinder varies in size and density since it is constructed of a different material. All are 1/2" in diameter and vary in length. This kit includes: 12 samples, an attractive wood storage rack coated in linseed oil for protection from wet specimens, and detailed instructions with theory. Samples include: aluminum, brass, copper, acrylic, pyrex, rubber, delrin (plastic), PVC, PTFE, nylon, poplar and oak.
