Homing pigeons use magnetism through tiny iron crystals in their beaks. Turtles use magnetism by sensing slight differences in magnetism throughout the ocean. It keeps them in the cycle of warm waters in a specific 8,000 mile path that they swim for years.

Why do people use magnetic north?
People use magnetic north as a reference point for navigation using a compass because the Earth's magnetic field causes the needle of a compass to align with the magnetic north pole. This makes it easier to determine directions when traveling.
Why is it better to use a magnetic compass to find directions more than the stars and the sun?
It isn't. Navigation by the stars is far more accurate than navigation with a compass, as magnetic north is different at different locations while north determined by the stars is the same at all locations.
Why do orienteering maps have magnetic North Pole instead of the true North Pole?
Orienteering maps use magnetic north because it aligns with the Earth's magnetic field, making it easier for participants to use a compass for navigation. Using the true north on maps would require constant adjustments for declination, which can be complex and time-consuming during an orienteering event.
What kind of energy does a compass use?
A compass does not use energy to function, as it relies on Earth's magnetic field for its operation. The needle in a compass aligns itself with the Earth's magnetic field, pointing towards the magnetic North Pole.
What made navigation independent of the direction of wind?
The invention of the compass, specifically the ability to use magnetic compasses for navigation, allowed sailors to determine their direction regardless of the wind's direction. This enabled them to navigate more accurately across vast distances on the open sea.
Why do people use magnetic north?
People use magnetic north as a reference point for navigation using a compass because the Earth's magnetic field causes the needle of a compass to align with the magnetic north pole. This makes it easier to determine directions when traveling.
How do people use a magnetic compass?
People use a magnetic compass to determine the direction of magnetic north. By aligning the compass needle with the Earth's magnetic field, users can find their orientation in relation to the cardinal directions - north, south, east, and west. This is a valuable tool for navigation, hiking, camping, and other outdoor activities.
Why is magnetic Declination is important?
Because if you need to use your compass to figure out which direction is north,then you need to know by how much the direction the compass points is wrong,and which way. That's the magnetic declination.
Why is it better to use a magnetic compass to find directions more than the stars and the sun?
It isn't. Navigation by the stars is far more accurate than navigation with a compass, as magnetic north is different at different locations while north determined by the stars is the same at all locations.
Why is a magnetic compass useless inside a submarine?
They're not - all submarines use both standard and electronic compasses for navigation.
Why do navigators use the magnetic compass?
Navigators use the magnetic compass as it points towards the Earth's magnetic North Pole, providing a reliable reference direction for navigation even when other systems may fail or be unavailable. This allows them to determine their heading and maintain a consistent course.
Why magnetic compass becomes ineffective in submarines?
The metal structure of submarines interferes with the Earth's magnetic field, causing inaccuracies in the readings of a magnetic compass. Additionally, the movement and changing direction of a submarine can make it difficult to rely on a magnetic compass for navigation. Submarines typically use gyrocompasses or other sophisticated navigational equipment instead.
When did the magnetic compass reach Europe?
The magnetic compass reached Europe in the late 12th century, likely introduced by Italian merchants trading with the Arabs. Its use quickly spread among European sailors for navigation at sea.
How can you use lodestone in a sentence?
I placed a lodestone near the compass to help with navigation.
What navigational tools did john Cabot use?
His Navigation tools were the magnetic compass,the log,the lead line,the quadrant or ustrolube, and dead reckoning.
What are the advantages of magnetic compass?
A magnetic compass is a reliable navigation tool that does not rely on external power sources. It is simple to use and provides accurate directional information even in areas with limited or no technology infrastructure. Additionally, magnetic compasses are durable and can withstand harsh environmental conditions.
Why do orienteering maps have magnetic North Pole instead of the true North Pole?
Orienteering maps use magnetic north because it aligns with the Earth's magnetic field, making it easier for participants to use a compass for navigation. Using the true north on maps would require constant adjustments for declination, which can be complex and time-consuming during an orienteering event.
