B.H Curve Apparatus

The B-H Curve Apparatus from Glass Agencies is a precision laboratory instrument designed to provide practical understanding of the magnetic properties of materials, magnetic hysteresis, and core characteristics in electrical and electronics engineering. This apparatus allows learners, students, and technicians to study the relationship between magnetic flux density (B) and magnetic field strength (H), enabling accurate plotting of B-H curves for different ferromagnetic materials. The instrument features a well-structured panel with clearly labeled input and output terminals, connection points for primary and secondary coils, and measurement points for voltage and current in the magnetic circuit. Built-in meters and visual indicators provide real-time readings, allowing users to observe magnetization, demagnetization, and hysteresis behavior under varying excitation conditions. Through guided experiments, learners can measure magnetic flux, calculate core losses, and determine key parameters such as coercivity, retentivity, and permeability, bridging theoretical concepts with practical observation. The B-H Curve Apparatus supports exercises in studying saturation characteristics, energy loss in magnetic materials, and the effect of material composition on magnetic response, providing hands-on experience in electrical machine design, transformer cores, and magnetic circuits. High-quality components, stable internal circuitry, and robust construction ensure reliable performance, accurate readings, and long-term durability during repeated laboratory sessions. The organized panel layout simplifies wiring, reduces setup errors, and encourages systematic experimentation, disciplined measurement practices, and precise data recording. This apparatus is suitable for engineering colleges, polytechnic institutes, vocational training centers, and electrical or electronics laboratories focusing on electromagnetic theory, magnetic material characterization, and instrumentation. Glass Agencies ensures that each B-H Curve Apparatus undergoes strict quality inspection to maintain functional accuracy, operational stability, and long-term usability in educational and research environments. Comprehensive manuals and guided experiment procedures provide step-by-step instructions for connecting the coils, adjusting excitation, recording voltage and current readings, and plotting accurate B-H curves. By combining precise measurement capability, clear visual feedback, organized construction, and flexible experimentation, the B-H Curve Apparatus from Glass Agencies equips learners with essential skills in magnetic circuit analysis, material characterization, and electrical instrumentation.
