Four weeks ago I was searching for an magnetizer that can revive my dead magnets (I killed them heating up at a high temperature, trying to encapsulate in a piece of glass), but I haven't found a instructable project that can help me, so with physics teacher's support I made one that works.
With it's help you can revive dead or old magnets, or you can magnetize things like screwdrivers, nails, paperclips, or any metal which can be a good magnet.
It looks like a game console, isn't it ?
This device is only a PROTOTYPE, so maybe I will try to make a big one that can magnetize your hammer.
Now let's start the work.
Step 1: Materials
The materials you need for this project are:
- a 1N4007 diode
- a DPST switch (I get mine from an old computer)
- a Push button switch (or how it is called)
- a jack and a capacitor(230 uF and 400 V) from an old power supply unit
- a plastic, wood, Plexiglas, or any material you found, but NO metals like iron, steel, aluminum, copper or any metal that are atracted
- a 15 W, 220 V lamp
- copper wire for making a coil (0.6 mm diameter for 800 turns)
- something on you can spool your coil (I use a plastic support from solder with inner diameter 20 mm [don't use something that have the inner diameter bigger than 20 mm because then your magnetizer will not work])
- a cable for your jack (I use an ordinary cable for PC supply), why I use it ? because it can be removed.
-two plastic panels (I made them because my case needs panels )
- 20 cm of thick copper wire (2-3 mm diameter)
Watch out how you handle the capacitor. If it is charged, and you touch it, you can die.
Try to make the capacitor's links with push button switch and with coil as short as you can,
