Step 1: You Will Need !

1.you will need an transformer

remove all the magnetic core plates from transformer , take your time and remove all plates without damaging the transformer coil

Now install all of the E shaped core plates back into the coil ,you can use some kind of glues to hold the plates (it will reduce 50-60Hz humming noise)

make sure coil is okay ,with your multimeter and it's time to plug it in.

Step 2: Safety First!

FOR SAFETY REASONS
You should connect an electric bulb in series with the transformer coil.

Step 3: Swipe It Over!

swipe your tool over this demagnetiser and slowly bring it away

DON'T PUT TOOLS TOO NEAR TO COIL ,THEY WILL ATTRACTTED HARDLY BY MAGNETIC FORCE AND CAN DAMAGE OR CAUSE SHORT CIRCUIT IN COIL.

Step 4: Before and After

You can see the difference, after demagnetise your tools it will loose it's magnetism.
