This course is one of the quickStep series offered by Siemens in Surge Protection. These are FREE on-line industrial knowledge building tutorials. quickSTEPs are a great start for industry novices moving into technical...

This activity is concerned with the magnetic field generated by a current-carrying wire. Two current-carrying wires are placed near each other as forces push them apart or pull them together. Materials needed,...

This lesson plan contains instructions for conducting an inquiry-based lab to investigate current-carrying coils in magnetic fields. Students construct a simple galvanometer from film cannisters and other...

The effect of the commutator is to produce a fixed spatial distribution of current directions in the armature conductors (shown as blue & green circles) independent of shaft rotation. The field created by these currents...

The objective of this Web site is twofold: (1) to describe the Hall measurement technique for determining the carrier density and mobility in semiconductor materials and (2) to initiate an electronic interaction forum...
