For demonstration of basic concepts associated with electromagnetic induction such as AC transformers, induced currents and their effects etc. Comprises a U-Core and I-Core, made from high grade laminations to minimize the induction losses, I-core sitting completely over U-core to provide a continuous rectangular annular laminated block. Arms of the U-core takes various coils included for different experiments. All coils are wound from enameled copper wire on rectangular plastic bobbin and are totally covered to prevent any contact with the winding. 4mm sockets provided for connections except for 600 turns coil that operates on AC mains and is provided with a 3-pin AC MAINS socket. Each coil clearly marked with number of turns and sits comfortably on U-core arm without air gap. Also included is a pair of soft iron pole-pieces to sit on top of U-core arms. One end of each pole piece is flat so that the pole pieces in situ provide a narrow gap with full cross-sectional area, while the other end in form of truncated cone providing narrow concentrated field between the poles. Following components are included in the apparatus:
* Laminated U-Core * 1 No.
* Laminated I-Core * 1 No.
* Stand for Dissectible Transformer: Cast metal stand consisting of a stable, non-skid heavy base with two removable clamping arms at the top.
* Soft iron Pole Pieces * 2 Nos.
* One coil of 6000 turns, maximum current 0.2A with one intermediary output corresponding to 2000 turns.
* One coil of 600 turns, maximum current 0.25A. Mainly to create the transformer primary. Provided with mains power connection.
* One coil of 1200 turns, maximum current 1.25A, with intermediary outputs corresponding to 400 and 800 turns.
* One coil of 72 turns maximum current 12A, with intermediary outputs corresponding to 6, 30, 54 and 66 turns.
Complete with Instructions on how to perform various activities.
* Dissectible Transformer with complete components

Electric Analyzer is a device for electric and redox tests. Portable didactic fixture consists of a console with output for two test tips, onoff switch and operating mode selector. At its upper console, light sources get activated depending on the conductivity of the tested medium level or direction of electrons in the redox process that is occurring between the two points tested. This equipment allow to test the conductivity of solids, liquids and solutions in five levels, conducting electrolytic processes in micro-scale and indication of the direction of movement of loads in redox processes. Power is supplied by a pair in built 9V batteries. Supplied with one set of test leads.
