Magneton is an Electric-type Pokemon that was first introduced in the first generation of the mainline Pokemon games. It evolves from Magnemite and it also has a third evolution that was later brought into the fourth generation of games, Pokemon Diamond and Pokemon Pearl, and that Pokemon is Magnezone.
For Pokemon GO players that are attempting to evolve their Magneton into Magnezone, they'll need to get their hands on a Magnetic Lure Module and 100 Magneton Candy. Players can get more Candy by making their Magneton their Buddy Pokemon and walking around with it or just acquire more Magneton's.
Once the lure is placed on a Pokestop, players can go to their Magneton's profile and click the 'Evolve' button. If enough Candy is gathered and the player is standing by the Pokestop, the Magneton will evolve into the powerful Electric/Steel-hybrid type Pokemon that is Magnezone. In Pokemon GO, its best moves for offense are Spark and Wild Charge, while its best defensive moves are Charge Beam and Wild Charge. Players will need to be careful when it comes to facing off against Ground, Fire, and Fighting-type monsters.
How to Get Magnetic Lure Module in Pokemon GO
Magnetic Lure Modules are used in Pokemon GO to attract more Pokemon to a Pokestop for 30 minutes. And like mentioned previously, this item can also be used to evolve specific Pokemon, such as Magneton and even Nosepass, which can evolve into Probopass -- a Rock/Steel-type Pokemon.
Players can head on over to the Pokemon GO shop and purchase the Magnetic Lure Module for 200 Pokecoins. The only way to get these coins without spending real-world money is by taking down local gyms with your Pokemon and keeping them there for as long as possible before getting taken over by another player. Of course, players also have the option to plop down some cold hard cash and skip out on the gym battles if they were to feel so inclined to do so.
As long as the module is placed on a Pokestop, other players can evolve their Magneton as well or use it to capture lots of Pokemon for half an hour. As of right now, Magneton and Nosepass are the only two Pokemon that can evolve by using this method. Over time, there could potentially be other Pokemon that also use this method in order to evolve.
Pokemon GO is only available on Android and iOS devices.
