A quiz completes the activity.]]> http://www.wisc-online.com/objects/index_tj.asp?objID=IAU13208 Terry Bartelt Learners study the interaction between the conductors of the stator and the armature inside a DC motor, which causes the shaft to rotate. A short quiz completes the activity.]]> http://www.wisc-online.com/objects/index_tj.asp?objID=IAU12708 Terry Bartelt In this animated and interactive object, learners examine the interaction between a conductor that represents a motor armature and a magnetic field that represents a motor’s main field. This interaction causes the shaft to turn.]]>
