The Handyman's Lifeline
- Hold the magnet in place with tape
- One of the two magnetic poles should face down onto the tube (i.e. perpendicular to the direction of air flow) so that the screw is attrachted with maximum strength to the magnet. Rod-shaped magnets are less convenient simply because they are more difficult to attach to the tube, but in general any magnet that is strong enough will do the trick.
- If you want to be absolutely sure that the screw will be caught, attach several magnets to the tube. These should be placed lengthwise, however, to ensure that the magnet fields do not neutralize each other. Obviously you want the screw to be undeniably attrachted to one of the magnetic poles.
- Run the vacuum cleaner at minimum power.
