What else can I help you with?
Does the black arrow on a compass point to the north or south?
It depends on a choice made by the person who made your compass; there's no universal standard. The easiest way to find out is to take the compass somewhere that you know which direction is north (at least to within 10 or 15 degrees), and see what way the arrow points.
What a compass needle be made from?
Answer:A compass needle can be made from any ferrous metal that can be magnetized.
What is a directional compass?
A directional compass is a navigational instrument that shows the user the cardinal directions: north, south, east, and west. It typically has a magnetic needle that aligns with the Earth's magnetic field to indicate direction. Users can use a compass to orient themselves and navigate in unfamiliar terrain.
Why does the magnetic north part of a compass needle point towards geographic north if like poles are suppose to repel?
Technically earth's northern magnetic pole is the south pole of its magnetic field. The north and south poles on normal magnets are derived from the fact that they are "north seeking" and "south seeking" respectively when made into a compass.
How old is the oldest compass in the world?
The oldest compass in the world is believed to be the Han Dynasty compass, which dates back to around the 2nd century BC in China. This compass was made of lodestone and consisted of a magnetic spoon floating in a dish.
An iron bar can be made magnetic?
Yes. Line the bar up pointing north-south, and whang on it with a hammer for a minute or so. If you hold a compass close to it, the compass should align with the bar, whichever direction it is pointing, showing you that the bar has been magnetized.
Where was the first compass invented in China?
The first compass was invented in ancient China during the Han Dynasty, around the 2nd century BC. It was a simple device made from magnetite, a naturally magnetized mineral, and a floating piece of lodestone pointing north-south.
Does south and iron attract or repel?
South and iron attract each other. The south pole of a magnet attracts the north-seeking pole of iron, which is why a compass needle, often made of iron, aligns with the Earth's magnetic field pointing towards the North Pole.
How can a simple compass be made using a magnet?
Repetitively stroke a pin which CID attracted to the magnet in 1 direction for two minutes (stroke, lift, back, down, stroke, etc.). Stick the needle in a cork and put it in some water - one end will point north and the other south.
What is the needle inside a compass made out of?
a certain kind of rock called lodestone that pint south because of the magnetic field

Where was the first compass made?
the first compass was made in China around the Qing Dynasty's rule.

The history of the magnetic compass?
A compass is an instrument containing a freely suspended magnetic element which displays the direction of the horizontal component of the Earth's magnetic field at the point of observation. The magnetic compass is an old Chinese invention, probaly first made in China during the Qin dynasty (221-206 B.C.). Chinese fortune tellers used lodestones (a mineral composed of an iron oxide which aligns itself in a north-south direction) to construct their fortune telling boards. Eventually someone noticed that the lodestones were better at pointing out real directions, leading to the first compasses. They designed the compass on a square slab which had markings for the cardinal points and the constellations. The pointing needle was a lodestone spoon-shaped device, with a handle that would always point south. Magnetized needles used as direction pointers instead of the spoon-shaped lodestones appeared in the 8th century AD, again in China, and between 850 and 1050 they seem to have become common as navigational devices on ships. The first person recorded to have used the compass as a navigational aid was Zheng He (1371-1435), from the Yunnan province in China, who made seven ocean voyages between 1405 and 1433. Compasses were common devices for travelers because they were necessary and practical items. The design of the compass did not change much between the 1600's and the 1800's. The compass also was known as a surveying compass or instrument, which was made by some clock makers. The surveying compass was a solar compass, which was different from the magnetic compass. Some compasses were made with wooden supports at the bottom and brass fittings on top. As with many other articles the emigrants had with them, compasses were made in New England states such as Pennsylvania (Schiffer, 352). Compasses were also imported from France and Germany.

What was William Gilbert's theory about why compasses worked?
He found that Earth has a magnetic field also known as magnetosphere
Why did Albert Einstein like science?
Einstein liked science because his dad gave him a compass and he wondered what made it point north and south and that motivated him to do what he did.
