Electromagnetism, Capacitors and Induction equipment is designed to support practical teaching and demonstration of core electrical and magnetic principles in physics classrooms, laboratories, and training environments. This category includes capacitor sets, air capacitors, inductance coils, solenoids, transformer kits, electromagnets, induction demonstrators, electrostatic models, and related experimental apparatus used to explore charge, capacitance, inductance, magnetic fields, and electromagnetic induction.
These products enable hands-on experiments covering key physics concepts such as capacitance variation, charge storage, electric field behaviour, magnetic field generation, electromagnetic induction, transformer operation, and current-induced magnetic effects. Equipment such as capacitor boxes and adjustable air capacitors support capacitance studies, while coils, solenoids, and electromagnets allow investigation of magnetic fields and inductive behaviour. Demonstration tools like Oersted’s law apparatus and Wimshurst machines provide clear visual understanding of current and electrostatic phenomena, making them suitable for structured teaching and laboratory demonstrations.
For quality and compliance reference, IEC 61010-1 is a current international standard covering safety requirements for electrical equipment used in measurement, control, and laboratory environments, supporting safe operation during experiments. IEC 60252-1 is applicable for AC motor capacitors and provides a recognised reference for capacitor construction and performance principles relevant to educational capacitor demonstrations. IEC 61558-2-6 is also a current standard covering safety of transformers, reactors, power supply units, and similar equipment, which is relevant for transformer-based teaching kits and power modules used in laboratory environments. These standards should be referenced only where supported by the manufacturer’s technical specifications and compliance documentation.
For LabChoice Australia customers, Electromagnetism, Capacitors and Induction products provide reliable, education-focused solutions for teaching electrical and magnetic principles through hands-on experimentation. They support clear concept understanding across school, university, and technical training environments where visual demonstration and practical learning are essential.
