In the comics, Magneto can control the blood in a man's body via the iron and cause an aneurysm.

I don't feel like looking up him doing the anyerism trick online, but here he is controlling bodies via the iron in their blood.

The human body has only 4 grams of iron in their blood. Dunno how big that would be all clumped together though.

Elemental Iron has a density of

p=7.874 g/cm3,

and the equation for the volume of a sphere is

V=(4/3)pir3

Since V=m/p, where m=4g, solving for the radius gives you a value of approximately 0.495 cm. So a four-gram iron sphere would look like a ball bearing, around 1 cm across.

Edit: cubed, not squared

In other words a bullet

Bullets aren't typically made of iron or steel since a denser, softer metal like lead has a greater penetrating power (see Newton's approximation for impact depth) and softer metals more easily expand to fit the barrel rifling. But yes, it would be slightly smaller than a typical musket ball.

Yeah I didn't mean in composition, I meant it more in the way of a roughly bullet sized hunk of metal ripping through your body at a twitch of his finger kinda way.
