The earth repells a lot of stuff. Such as magnetic particles (via the Van Allen radiation belts), As we are ON the surface of earth, we would not see any physical repulsion (like holding a piece of metal and then it flys away from us). Although that would look pretty cool, huh?

The Earth is a fairly weak magnet, so the amount of magnetic force on anything magnetic is less than the gravitational force. That's why a magnetized piece of iron and a piece of non-magnetic material (such as lead) will fall pretty much the same way if you drop them. As others have pointed out, a balanced compass needle is affected by the Earth's magnetic field.
The Earth's magnetic field does, however, deflect ionized particles from the Sun. This is why there is aurora near the polar regions and not anywhere else.

The earth's magnetic field does repel radioactive particles. Electromagnetism only requires that the poles be negative and positive relative to each other. Both poles can be negative as long as one pole is less negative than the other and the entire magnetic field will be negative relative to more positive particles which may also be negative but less negative.

You mean--why doesn't the Earth repel other masses (like human beings?)
The Earth itself has mass, and everything which does also has a certain value for their pull on other masses due to gravity. The larger the mass, the larger the quantity for its gravity on another object.
Because the Earth has a signficantly large gravitational pull relative to everything upon it, and because gravity is an attractive force only, nothing is repelled (i.e., animals, objects, etc...)

The earth does repel things - specifically, the end of a compass needle is repelled by one pole and attracted by the other.

mind you... don't mix up the attractive force of earth due to gravitation and the magnetic forces. we are attracted by the earth due to gravitation, while the earth attracts or repels other magnetic materials like a normal magnet would do!

Becouse any repulsion is cancelled out by an equal and opposite attraction by the opposite pole.
