The last answer was close. The ball would oscillate back and forth (up and down), because of gravity, not magnetic force.
There is magnetic force inside the Earth, and it is not lined up with the north-south poles. The magnetic force would attract the iron ball, so it would move sideways a little bit. But the magnetic force is very weak compared with gravity.

Morning fox is correct if we constrain the question.. Actually, electromagnetic force is MUCH stronger than gravity and the word IRON in the questions begs us to consider the problem of keeping the ball centered in our trans earth tunnel. After raising the funding to dig the tunnel, magnetic centering will be trivial compared to preventing the walls of the tunnel from melting.
What keeps you from going through the sidewalk to the center of the Earth is the electromagnetic fields around the molecules of your shoes and the cement.
No matter how fast you fell, the surface of the earth would stop you. Maybe at the surface surface. Maybe 20 ft deep, maybe you would dig a crater a few miles across. But the ELECTRONS are so strong in their repulsion of each other that they will overcome gravity.
Why are electrons so much stronger than gravity?
Electrons are the most popular form of Matter. Matter is a special state of PHOTONS. As Einstein pointed out, there is one heck of a lot of energy coiled up in matter. Matter is SAGANS (1 Sagan = billions and billions) of photons doing intricate dance patterns in 10 or 11 dimensions. What makes electrons so forceful is that they have the ability to catch and emit photons. Light, WI-FI internet, chemical reactions, almost everything takes place because of this special power.
Gravity is merely a DISTORTION of SPACE even the apparent paths of photons follow its curve. Gravity has no ENERGY of its own. The only energies of gravity are the result of matter interacting with this distortion. Thus the simplicity of newton's math.
Oh, yeah, like morning fox said magically nullifying all other forces, the ball would oscillate. Bounce a ball on a flat surface, and you get to see the same experiment in a dimensional mirror image. The equations would be the same. (you do 'em, i hate math.)

It will melt. The core of the earth is too hot, even for an iron ball. Hypothetically, if it did not melt, it would continue wavering up and down, towards the poles, due to the magnetic attraction of the center of the eart.
