Description
These high-quality coils and laminated iron core provide an effective introduction to electromagnetic induction in transformers. Purchase them individually or as a complete set. Each coil is labeled with the number of turns, the direction of the winding, and the maximum current. Use them to investigate:
Electromagnetism: Show how the magnetic field can be increased by increasing the current, by adding an iron core, or by using a coil with more turns.
Induction: Pass a magnet through a coil and detect the resulting electromotive force (EMF) with a galvanometer. Show how the EMF depends on the number of turns in the coil and on the relative velocity of the magnet and coil.
Transformers: Mount coils onto the U-shaped iron core to demonstrate mutual inductance and transformer theory. Then connect a load to investigate power transfer. Investigate basic transformer theory with an AC power supply and a voltmeter. Advanced principles require a high power output function generator and an oscilloscope. For more in-depth experiments, use a computer with PASCO’s 850 Universal Interface or 550 Universal Interface.
