Method
Place the stand on the table and screw the two boss clamps on. Place the clamps in the boss clamps and tighten the screws. Open the bottom clamp wide enough for the solenoid to fit in and then tighten the screw. The solenoid needs to be put in upside down. Hook the spring onto the clamp and then attach the bar magnet. The bar magnet needs to be hanging down so that it is ¼ of the way down on the magnet or ¾ of the way down in the magnet (as shown in the diagram below).
