-A permanent magnet sits between parallel metal rails which are connected to a galvanometer.
-Place the loose metal bar inside the magnet across the rails.
-Close the switch, allowing current to flow through the bar.
-The bar will travel along the rails.
-Use the special projectual which contains fillings emersed in a liquid.
-The magnet will take about 3 seconds to fall through the tube, while the "dummy" magnet will fall through very quickly.
-Plug in the cathode ray tube.
-Deflect the beam of the CRT by holding a permanent magnet near the edge of the tube.
-If the beam disappears you are holding the magnet too close.
-OR deflect the beam by attaching a battery to the binding posts and adjusting the variable control knob.
-OR Connect the battery directl to the deflection plate terminals.
