temporarily magnetize tweezer?

I know I have done this before but I cannot for the life of me remember how- sil is trying to put new screen on iphone and the screws are so tiny he cannot get them started. I was thinking if he was to magnetize them it might help. How do you magnetize them?
 
what about a tiny screw driver? I used to have a tool for holding tiny screws like that - darned if I can find it!
 
Have you tried a points screw starter, like the old ignition tune up tool set from Snap-on had? It has a spring loaded flat blade screwdriver, with a section, in the middle, that twists, against the flat of the screw, to hold it to the tip of the screw starter. There was also a phillips version of the screw starter, that forced the tip of the screw starter apart, to hold a phillips screw.
 
If you have a good magnet, rub the screwdriver across it several times, generally that will magnetize a screwdriver for a while. But, as someone else already said, often those teeny-tiny screws are stainless steel and may not take to a magnet.
 

I've broken my iphone screen more than a few times and have changed a few others for famil members. I bought a kit from ebay when I did my first one. The screwdrivers they come with are special to fit the tiny screws. I found that more often than not, they are slightly magnetic already. The last one I did, one screwdriver did not want to hold the screws, so I used a magnet from the refrigerator and wiped it across the screwdriver. It magnetized it enough to hold the screws for the reinstall.
 
An object, can be magnetized by by passing the item through the loop of a soldering gun while the iron is powered. This will not produce a very strong magnet
 
HUH????


Typical soldering irons are AC and will DEMAGNETIZE an item, if any thing.

Much like the "degaussing coils " of old that every TV shop had to erase residual magnetism from color TV CRT"s... heck I think i SILL HAVE ONE.
 
As noted if the object to be magnitized is not iron, nickel or cobalt or have a percentage of one of those in it, it will not work. Those are the only metals with a magnetic attraction.
 
I have a small tool from HF, has 2 holes in it. One is rectangular, pass a tool through it and it's magnetized. The other hole is odd shaped, pass a magnetized tool through it and it will demagnetize it. I can comprehend how to magnetize and object, but to demagnetize with just a little thing in your hand is beyond me. At work our bearing heaters demagnetized the bearings but they were AC.
 
I think AC works to demagnetize because the changing current flow from positive to negative through a coil randomizes the magnetic charges.
 
I have tried poking the screwdriver into a glue stick and it has worked to hold these wee screws. I have also used a very light touch of superglue with good results.
Both work better than trying to use tweezers.
 
NOW you"re talking. Insert item into loop of soldering iron tip, and click iron on and off. If you hit the peak of the AC current cycle the item will be magnetized.

If not, repeat.
 
Old mechanics use a dab of grease or Vaseline on tip of screwdriver if they don't have or don't want to use magnetic screwdriver.
