I recently bought a packet of these to use with the magnetic sensors.

As soon as I released the plastic packaging around the magnets they all flew out and neatly joined themselves together!

Does it matter if they are stored like this if it does how do you manage to get them back in the plastic packaging as they really do seem to have a life of their own!

Try putting a steel ruler under the packaging, then placing the magnets into the 'pockets' - the steel rule should hold them in place. Then when they're in the pocket, put some sellotape over the top to stop it jumping out 🙂

Can you imagine just how stressed the guys packing them at our suppliers became.... It needed a special magnetic jig to hold them in the packaging until they were taked in place.

Anyway - they are fine sored like that. Put them in a small ziplock bag if you can.
They will last almost forever sand can only come to harm if the metal plating on them is damaged (neo magnets do not like being exposed to air).

Ahjay,
(neo magnets do not like being exposed to air).
So do we need to coat them in use under rolling stock, locos etc?
Is it oxidation?
Would a coat of nail varnish help? Coloured or clear?
Just wondering.

Peter, they are already plated so will be fine as is.

If you want a "belt and braces" approach then by all means add a varnish coat etc, but as long as the plating is there it will not matter really.

However if you are tempted to drill or cut them for any reason, then definitely re-seal them so no air hits the Neodymium... or they will literally oxidise until they turn to dust.

Thanks AHJAY I had imagined the suppliers guys running round the factory trying to collect them! Brian

Thanks for the clarification,
that is what l suspected.
I've had no issues in the several years of use, they have indeed been ''fit and forget''.
l just did not want future issues with where some of them are fitted.
Thanks again,
Pete
