I would suggest using a Pokémon with the ability Frisk, saves having to waste loads of Poké Balls to try and capture one holding a metal coat. However, I'm unsure of Magneton can actually be found wild holding a Metal Coat in this game.
A Metal Coat can be found in New Mauville. The Metal Coat is on the right of the machine.
The Metal Coat can be found on Iron Island.
Give it a metal coat and trade it. The metal coat can be found on on five island
On Diamond and Pearl you can find the Metal Coat on the Floor in Iron Island. In Platinum the Metal Coat can be found in the Iron Head Ruins also found in Iron Island (you will also find Registeel there)

Scyther can evolve into Scizor when traded while holding a Metal Coat item. Metal Coat isn't a very rare item and can be found held by wild Magnemites.
A metal coat makes an Onix evolve into a Steelix.
No, of course not. You have to trade it with a metal coat on
All I really know is that you can find one in iron island after you help riley. There should be two exits. Take the one that leads upwards and there will be a pokeball in the center of the room. Take it then you should get a metal coat!
Onix needs the Metal Coat in order to evolve into Steelix once it is being traded and in Pokémon Gold, Silver, Crystal, HeartGold and SoulSilver it could be found in the SS Aqua. In Pokémon FireRed and LeafGreen the Metal Coat could be found in Memorial Pillar and Trainer Tower. The Metal Coat would be found on Iron Island in Diamond, Pearl and Platinum while it would be available in the Clay Tunnel and in the Chargestone Cave in Black 2 and White 2.
the Pokemon that evolve with metal coat are steelix and scisor
You dont, you make the pokemon hold it
