Sorry but he doesn't evolve by level only by trading but he has to be holding a MAGMARIZER
to evolve after trade or
1: Catch a Magmar near fuego ironworks
2: If its not holding a Magmarizer get one in route 214 past the cave through the grass or use rock smash to get there now get the pokeball it will be a Magmarizer
3: Go to jubilife city to the gts global trading put magmar with Magmarizer but put you want to get something hard
like a chimchar lv 100 .
Now save wait for tommorow or just wait awhile.
Tip: This can work with Electebuzz with electrizer something like that
If that doesn't work give Magmar a fire stone at lv 35
If that still don't work check the internet but put rude coments on me I'm only 6 yrs old & a huge pokefan
