In "olden" days, poles might have been made out of aluminum, which is pretty much the same material as the bar that vaulters try to vault over. However, nowadays vaulters use poles made of fiber-glass, which is much lighter and more flexible. Pole lengths may vary, but the minimum is usually (unofficially) around 12ft. and the max depends on the height you are attempting to vault over.
No, a magnet's poles do not have the same charge. One pole is a north pole and the other pole is a south pole, resulting in opposite charges.
the south pole attracts the north pole. That means the opposite poles attracts and same poles repels.
the south pole attracts the north pole. That means the opposite poles attracts and same poles repels.
The north pole of one bar magnet will attract the south pole of another bar magnet, while the north pole of one magnet will repel the north pole of the other magnet, and likewise for the south poles. This is described by the principle that like poles repel and opposite poles attract in magnetism.
Yes, like poles repel each other, so the north magnetic pole would repel the south magnetic pole. This is due to the principles of magnetism where opposite poles attract and like poles repel.
False. Opposite poles attract. Same poles repel.
Earth has two poles: the North Pole and the South Pole. The South Pole is located in Antarctica, while the North Pole is in the Arctic Ocean. The Earth's geographic poles are the points where its axis of rotation meets its surface.
No, in a dipole moment the poles have opposite charges. One pole will be positive and the other pole will be negative. This creates a net dipole moment.

Magnetic poles attract each other if they are of opposite polarity (north pole attracts south pole) and repel each other if they are of the same polarity (north pole repels north pole or south pole repels south pole). They do not exhibit neutrality towards each other.
Like magnetic poles repel. For instance, the North Pole will always repel another North Pole. Such poles have the same charges and cannot transfer them to each other, a condition that would lead to attraction.
