If a magnet is attracted to a metal object what can you say about the pole of the magnet and the pole of the object?
A. The poles are opposite
B. The poles change
C. The poles are not changed
D. The poles are the same

A. The poles are opposite

Explanation:

Magnets are object that produce magnetic fields, which are regions of space that exert a forces on charged particles in motion or on other magnets.

Every magnet has 2 opposite poles, which are labelled by convention as North Pole and South Pole; the lines of the magnetic field of a magnet go out from the North Pole and go into the South Pole.

Magnetic poles always exist in pair: it means, every magnet always contains a North Pole and a South Pole. If a magnet is cut in a half, each half of the magnet will still have a North Pole and a South Pole.

Each pole exerts a force on another pole; in particular, we have:

- Like poles (north-north or south-south) repel each other

- Opposite poles (north-south) attract each other

In this problem, a magnet is attracted to a metal object: this means that the two poles must be of opposite polarity. Therefore, the correct option is

A. The poles are opposite
