To get a Magmarizer in Pokemon Diamond you need a copy of Pokemon LeafGreen in the GBA slot of your DS. With Pokemon LeafGreen in the GBA slot of your DS wild Magby should start appearing in route 227 and Stark Mountain. Wild Magby have a chance to be holding a Magmarizer for you to catch or steal using moves like Thief. Note your DS must be turned off before you insert the copy of Pokemon LeafGreen into the GBA slot.
Infernape does not exist in Pokemon LeafGreen. Infernape didn't exist until Diamond/Pearl/Platinum, which was released after LeafGreen.
