The reason that some magnets push or pull away from another metallic object is the result of tiny electrons and protrons. These spin around atoms which are the building blocks of all material.When a magnet or object has more protrons than electron,it has a positive charge to it.When a magnet or object has more electron than protrons,it has a negative charge to it.A positively charged objcet will pull toward a negatively charged object.Every magnet has both a north and south pole.If you try and push the south pole of one magnet toward the south pole of another magnet,they will repel each other and push away.If you break a magnet in half,the two new magnetic pieces will each be assigned a nwe north and south pole.If you want to conduct an experiment with magnets,just gather together som thumbtacks,staples pr paper clips.Hold a magnet in your hand and see how many you can attach to one end of the magnet.
