CLARK — Fourth grade students at the Frank K. Hehnly School in Clark under the supervision of substitute teacher Jackie Grigoli learned how to make an electromagnet using a battery, a bolt, and wire. Students coiled the wire around the bolt and attached the wires to the battery. This made the bolt act as a magnetic field. Students were able to pick up paper clips with the bolt, which proved its magnetic properties. The class also learned that they could make the electromagnet more powerful by adding more coils of wire or another battery. In the picture above, students Gabby Prestinari, John Petrucci, Elthon Gonzales, Olivia DeMartinis Jackie pose with their electromagnet that attracted over 20 paper clips.
