How can you test if a material is magnetic?
Using a compass; You move the compass around the object and if the hand in the compass goes mad, then it is a magnet To test how something is magnetic: See if it sticks to a magnet. It will only be magnetic if it is made from nickle, iron or cobalt. Steel is also magnetic because it is made mostly from iron. Hope this helps x
How navigators and sailors used magnetic compass?
The Earth's magnetic field is what makes the common magnetic compass work. From its invention until the advent of newer technologies beginning around the turn of the 20th century, the magnetic compass, together with the sextant and the chronometer, constituted the primary tools of the navigator. Of course, the compass' primary role was to facilitate steering ships on the right heading under conditions where the Sun and stars could not be seen.
If a material has a hardness of 8 can it not be scratched by a material with a hardness of 7?
Yes, a material with a hardness of 8 can scratch a material with a hardness of 7, but not the other way around. Hardness is a measure of a material's resistance to scratching, so a material with a higher hardness value can scratch a material with a lower hardness value.
How do earths magnetic properties explain how a compass works?
Earth acts like a giant bar magnet with a North and South pole, which creates a magnetic field. A compass needle is a small magnet that aligns itself with Earth's magnetic field to point towards the magnetic North pole. This allows users to determine their direction by reading the compass needle.
Can a electric current affect a compass?
Yes. An electric current is surrounded by a magnetic field, and this will affect a compass. Please note that this is more noticeable in the case of DC - for AC, the current changes all the time, it changes very quickly, and the AVERAGE value of the magnetic field is zero.
What characteristic of iron would it a bad material for the housing around a compass?
It could not be used because it attracts magnets and a compass is a specialist form of magnet, utilising the magnetic properties of the earth to give a reading. Compass housings are invariably made of brass, aluminium or plastic.
What characteristic of iron would make it bad for materials for the housing around 2 compass?
Iron is a magnetic material, which could interfere with the functioning of the compass needle by causing deviation from true north. This is known as magnetic interference. To prevent this issue, materials with low magnetic permeability, such as aluminum or non-magnetic stainless steel, are preferred for compass housing.
What characteristics of iron would make it a bad material for the housing around A compass?
Iron reacts with oxygen and water to form rust. Not a good thing for a compass.
What charactericof iron would make it a bad material for the housing around a compass?
Iron is a poor choice for a compass housing because it is easily magnetized, which can interfere with the compass needle's ability to point accurately to magnetic north. Iron is also prone to corrosion, which can affect the compass's functioning over time. Using non-magnetic and non-corrosive materials, such as brass or aluminum, would be more ideal for compass housings.
What is the box that surrounds around a compass called?
The box that surrounds a compass is called a compass housing or compass casing. It helps protect the compass needle and dial from damage and external interference.
How do you tell if its a magnet or a magnetic material?
One way is to try to stick it on your fridge. You can also see how it acts around a compass and around known magnets. If the needle of a compass moves around it, or it repels or attracts a known magnet, then you know it is magnetic.
When was compass invented?
The first compass was invented around the year 1044. Modern liquid magnetic compasses stem from the mariners compass that was invented in Europe around 1190.
Where in Texas was the compass developed?
The compass was developed in China around 247 B.C.
Where was the first compass made?
the first compass was made in China around the Qing Dynasty's rule.
What would happen if you brought a compass in to space?
it would spin around and around.
What year was the magnetic compass made?
The magnetic compass was invented in ancient China during the Han Dynasty around the 2nd century BC. It was a significant navigation tool that revolutionized travel and exploration.
Who invented the magnetic compass.?
The magnetic compass was made in China the second century AD. The Norse seamen of around 900 AD had magnetite rock that they used as a magnetic compass.
