How important is a magnetic compass?

The magnetic compass was an important advance in navigation because it allowed mariners to determine their direction even if clouds obscured their usual astronomical cues such as the North Star. It uses a magnetic needle that can turn freely so that it always points to the north pole of the Earth’s magnetic field.

What are uses of compass?

The compass is used for navigation location and direction. People use it to find their way whether it is on a hiking trail or on a trip to a new location. It is an instrument composed of a suspended magnetic pointer that is attracted to the polarity of the North Pole.

What is the importance of magnet to help those things function properly?

Magnets are essential in today’s electronic technology. Magnets are useful fun and even a little mysterious–they can repel as well as attract. The science of magnetism is tied to the modern science of electricity but has been recognized for thousands of years.

How do magnets move objects?

Attach a magnet to an object. When another magnet is brought near it the two magnets will either be attracted or repelled and the object will move. For example if a magnet is attached with a string to the middle of a horizontal pencil the apparatus will behave like a pendulum when another magnet is moved around it.

How do magnets work for dummies?

All magnets have north and south poles. Opposite poles are attracted to each other while the same poles repel each other. When you rub a piece of iron along a magnet the north-seeking poles of the atoms in the iron line up in the same direction. The force generated by the aligned atoms creates a magnetic field.
