to find magmar on Pokemon platinum you must first have a Pokemon who knows surf and go to floroma. Go east (beetween windvalley and floroma) till you see a tiny bridge. use surf there and keep going west and up till you get to the furgo iron works in the grass there will be magmars
Magmar is found in the grass at mt ember.
you can find magmar on grassy patch on mountain ember in island one
Magmar is a Pokemon exclusive to leafgreen so no you can't get it.
you find magmar in the burned tower in ercuteak city
I found it easier to find magmar in the wild in the grasses on Mt Ember ( on one of the unlockable islands -1 - 7 ) , it was so much easier !! , im not to sure you can find magmar in the poke-mansion
The only way to obtain Magmar in Pokemon FireRed is to trade it from LeafGreen.
Capture a Magmar then find an item called a magmarizer make Magmar hold this item then trade it.
To catch Magmar you have to go to the "Burned Tower". Walk a lot and you will find it.
To evolve Magmar, find a Magmarizer. Take the Magmarizer and Magmar to Luminous Spring. It should evolve.
In the Pokémon game you can find and catch Magmar near the Fuego Ironworks. This location can be reached by surfing and the Magmar is found in the grassy areas.
go to stark moutain and try to find a magnimizer and then give it to magmar (get magmar by migrating from leafgreen) and then trade with the magmar holding the magnimizer. (hoped it helped)
Magmar is VERY rare and you have to find it past kindle road but not inside the mountain
