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?
Nikolay [14]

Answer:

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
