As he was simultaneously struck in the face and had his prize ripped right back out of his hands, Magneto realized the foolishness of having dropped his shields even for a moment. Lesson hard learned. With a snarl he put his electro magnetic barrier back up, trying to claw the strange webbing from out of his eyes. To add insult to injury the Spider idiot was blathering on, making inane quips that only enraged Magneto further. The moment his eyes were clear he turned and savagely ripped a light pole from the ground, twisting it into a band that went hurtling towards Spider-Man to hit him full force and snake around his body. Captain America's warning to his comrade came a little too late; maybe the cretin should've kept his mouth shut and his webs to himself.
With another gesture as if he were swatting a fly, Magneto sent the entrapped form of Spider-Man into the air, dragged up by the metal ensconcing his body and then wantonly hurled out over the city away from the tower and the fight. Magnus didn't care where he landed he simply hoped it hurt. Perhaps that would silence the insolent child.
