Electromagnetics Demonstrator A compact teaching instrument for demonstrating the magnetic field around a current carrying conductor and verifying the righthand rule and linear current magnetic field. Key benefits Provides a clear, visual demonstration of the magnetic field produced by an energized conductor for classroom and laboratory instruction. Supports handson verification of the righthand rule by allowing students to reverse current direction and observe needle response. Compact and portable dimensions suit desktop demonstrations and lab benches. Product highlights Name: Electromagnetics Demonstrator Dimensions: Length 250 mm, Width 180 mm, Height 122 mm Weight: 509 g Power requirement: DC 6V power supply for operation Color and needle options: Black version with wingshaped magnetic needle; Orange version with strong magnetic needle Package includes: 1 Electromagnetics Demonstrator Function and operation Designed to show that a magnetic field exists around a conductor carrying current and to illustrate the magnetic field of a linear current. Setup: Place the demonstrator on a flat surface and mount the large magnetic needle on the needle tip. Adjust the base until the needle is stable and the wire is aligned parallel to the magnetic needle. Energize with a DC 6V power supply. The magnetic needle will swing as the magnetic field is produced around the conductor, allowing observation of field direction and strength changes. Reverse the current direction to observe the corresponding change in needle orientation and confirm the righthand rule. Practical attributes Size and weight make the unit easy to position on a desktop or lab bench while providing stable demonstration behavior. Clear needle movement provides a visible, reliable indicator of magnetic field presence and direction when current flows. Two needle styles let instructors choose the visual and response characteristics suited to their demonstrations. Use scenarios school physics classroom demonstration to introduce magnetic fields around currents and to verify theoretical rules from the curriculum. Lab exercise for students to set up experiments, change current direction, and record needle responses for data collection and discussion. Science fairs or instructorled demonstrations to visually illustrate electromagnetic principles to small groups. Contents and compatibility Includes one Electromagnetics Demonstrator. Requires an external DC 6V power supply for operation. No additional parts are included. This instrument is designed to meet instructional needs in standard physics curricula for demonstrating the magnetic effects of electric current and for handson verification of electromagnetic principles.
