Electromagnet Experimenter This classroom electromagnet kit is designed for junior school physics group experiments on electromagnets. It provides a clear, handson way for students to explore how coil turns, tapping points, core shape, and simple power sources affect magnetic behavior. Key benefits Straightforward setup for group activities: compatible with common classroom cores and a single No. 1 battery providing 1.5V power. Versatile wiring and configuration: two separate coil sets with midpoint taps and three binding posts each allow a range of experiment configurations without rewiring the whole apparatus. Clear demonstration of electromagnetic principles: coil turn counts and interchangeable core options make it easy to compare how construction affects magnetic properties. Durable, focused design: 100% Pure construction supports repeated use in teaching environments. Main features Power requirement: designed to operate with one No. 1 battery supplying 1.5V. Coils: two independent sets of coils, each with about 200 turns and a tap at the midpoint for variable turn selection. Connections: each coil set includes three binding posts for flexible connection options and easy reconfiguration during experiments. Core compatibility: coil sets can be used interchangeably with Ushaped cores and cylindrical cores to demonstrate core shape effects. How it helps teachers and students Simplifies comparison experiments by letting students change the number of active turns using the midpoint tap and observe resulting differences. Reduces setup time for group work with multiple binding posts, so several students can test different circuits in sequence. Encourages exploration of core geometry by making Ushaped and cylindrical core trials easy and repeatable. Typical use scenarios Classroom demonstration: Show how a 1.5V supply energizes the coil and how changing the tap or core shape alters the magnetic response. Student lab activity: Small groups measure and record how coil turns and core type influence the pick up of ferrous objects or the deflection of a compass. Handson enquiry: Use the three binding posts per coil to build simple series or parallel arrangements and compare results during a guided lesson. Specifications summary Material attribute: 100% Pure Power: No. 1 battery, 1.5V Coil configuration: two sets, about 200 turns each, midpoint tap Connection: three binding posts per coil set Core compatibility: Ushaped cores and cylindrical cores, interchangeable This Electromagnet Experimenter is a practical tool for junior physics education, offering clear, repeatable setups and flexible configurations to support group learning and demonstration of basic electromagnetic principles.
