Default Magnet charging--i need to get this straight

On Magnet charging--I need to get this perfectly clear!! I determine the poles on the magnet---I have already have the charger marked for poles--take the magnets off the mag-[KW-hi-bar] one at a time and charge them by putting them on the charger opposite poles for a couple bursts of about 10 seconds ----tap the magnets lightly while charging--the magnets go on the charger -with the north on the magnet to the south on the charger!--if this is correct----say yea!!--if not, tell me in understandable terms [EXACTLY] how to .
this is the only mag I have like this--I would like to keep it.
thanks d,j,

yea, that is what the instructions on mine say but nothing is mentioned about tapping on the magnets while charging. My instructions say 20 seconds on 20 off for three cycles. I hope this helps

Tapping on the magnet supposedly gets those molecules excited so that they will more easily align themselves with the magnetic field. I suppose you could warm their little bodies and accomplish the same thing.

Anyway, BEFORE you remove the magnet from the charger, you need to attach a KEEPER and remove the keeper only after you've placed the magnet back onto the magneto. Actually, it's much easier to charge the entire magneto on the charger. You can use extra chunks of iron to assist with the path.

I was told years ago by a very good magneto mechanic that it is not necessary to remove the magnets from the magneto in order to recharge them. I have recharged a number of magnetos this way with very good results

I forgot to mention the armature needs to be insulated "held up" with a couple of pieces of wood or plastic not down as the previous photo shows. I am speaking of a wico mag.

I've not had to monkey with blocking the armature up when I charge a Wico. When I push the charger button, the Wico armature JUMPS up off the frame anyway!

Exclamation Re: Magnet charging--i need to get this straight

For best results, if possible, charge magnets on mag. Charge nested magnets as a group. If you charge individually, and one magnet is weaker, it will draw down the charge on the others. The weaker magnet acts like one that is reversed, it will cause the others to weaken. Make sure to keep a keeper on the magnets until the mag is fully assembled. While charger is on, tap magnets lightly with a brass hammer (do not use steel!) Good luck
Andrew

When i charge magnetos i allways do it with the magnets on the magneto, I dont bother with the tapping with a hammer as it sticks to the magneto and due to the strength of the field, suppose you could do it with a brass or copper hammer though?, most inportant is to get as much surface contact between the pole pieces and the magneto make sure there are no un even surfaces on whatever blocks on metal you use to make up the gaps.


happy zapping

What does a iron melecule look like? If it can move in the magnet you should be abel to see it, i would think.
