Fact Sheet: Sources of Polychlorinated Biphenyls

Electromagnets Oil-cooled electromagnets are constructed with coils immersed in transformer oil to prevent over-heating and shorting. Used in cranes for picking up metal and for metal separation in recycling operations (metal scrap yards, tire shredding, concrete crushing, slag operations, etc.). Miscellaneous electrical equipment

Type CO Overcurrent Relay Instruction Leaflet

2.0 CONSTRUCTION AND OPERATION The type CO relays consist of an overcurrent unit (CO), an indicating contactor switch (ICS), and an in-dicating instantaneous trip unit (IIT) when required. The principal component parts of the relay and their location are shown in Figures 1 through 5. 2.1 ELECTROMAGNET The electromagnets for the types CO-5, CO-6,

Lab 7: Magnetism and Electricity - University of Oregon

electromagnets have a magnetic core (iron, nickel, etc.) for this reason. NAME_____ DATE_____ 6 Experiment 2: We’re makin’ electricity here! Introduction: In Experiment 1 you found that passing electric current through a wire arranged as a coil created a magnetic field. A battery was used as a source to push charge through the wire. ...
