where to buy soft iron rods

[Ken Williams]

anyone know where I can buy soft iron rods in various sizes and shapes?
Seems to be a nightmare to find anything.

thanks.

these days a good substitute is mild steel.
I'd try a hardware outlet, if they dodn't have what I wanted I'd go to
a metal supplier like "metalcorp"

steel tie wires are mild steel, fencing wire is not
many bolts are mild steel.

I used to cut lengths of wire from coat hangers and bundle them to make
a soft iron core.

is where you want to ask. You don't say
where you are located, whch makes a huge difference of where you can
find it.

I'm in canada. ebay doesn't seem to have much when I search for "soft
iron core".

Sounds as if you are actually looking for magnetically soft iron rather than
mechanically soft iron (they are fairly closely related, but not an exact
match).

If it's for an AC application, take a hacksaw to a microwave oven transformer.
If it's a DC application, look for hot rolled, low carbon steel. probably
AISI 1005 will be as good as you can get. High silicon magnetic steels tend to
be fairly hard to obtain in small quantities and expensive except by robbing
existing equipment (like MOTranfromers).

What about pulsed DC? thats considered AC?

Its for electromagnet coils that will be pulsed with DC. I want a good
iron core to concentrate the magnetic flux.

Tehn you need mu metal. Hard as hell to find!

Coat hanger wire is made out of soft iron. Cut to length and pack into a
cardboard ( or whatever ) tube and wind your coil on that.

You should be able to find a lot of them. They seem to multiply in
closets. ;-)

Is there a simple test to test the difference between mild steel and soft iron?

I have a bunch of them. I had to buy them in bulk from Bangladesh.

You can go to eBay to get them The item # is 300435220310

Also, if you'd like to check out my YouTube page, I do a lot of work with electromagnets and magnetic motors there.
