A screwdriver should be 100% efficient, if there are any small losses they will be due to deforming the screwhead, or frictional losses on the screwhead.
You just stroke it in the same direction a few dozen times with just one pole of a powerful permanent magnet.The screwdriver must be made of of iron or steel: it won't work if the screwdriver is made of something like brass, aluminum or plastic because those materials are non-magnetic!Lots of people try to make a magnet using both poles of a horseshoe-shaped magnet but then it won't work as well because the second pole of the magnet will reverse the magnetising effect of the first pole.All you have to do is keep stroking the metal with just one pole of your magnet, pressing hard and always going in just one direction only and then pick up the magnet at the end of each stroke.Stroke the metal over and over like that with just one pole of your magnet until the metal of the screwdriver gets magnetized enough to pick up other pieces of metal, like a smaller screwdriver or some metal paperclips.But be sure to to try your magnetized screwdriver only on other things that are also made of a magnetizable material such as steel.
