Is a sewing needle magnetic?
Sewing needles are almost always made of steel, which is a magnetic alloy of iron, which is, itself, magnetic. Sometimes we put a bowl of water on the table, rub and tap a sewing needle with one end of a permanent magnet for a few seconds, float the needle on the water (a hint of oil on the needle might help), and construct a homemade magnetic compass.
What direction does a compass always point?
Magnetic northNorth.In line with the earth's magnetic field.A way to remember the four directions on a compass is Never Eat Soggy Waffles or Never Eat Slimy Worms.magnetic north
What did Charles Fredrick Weisenthal want to do with the sewing machine he invented?
He wanted to add a double pointed needle with an eye at one end.
What do you call the craft where you knit one row then crochet a row using a long needle with a hook at end?
You might well be talking about an afghan stitch, which is all done with one long needle with a hook at one end and some kind of block or barrier at the other. You can Google afghan stitch to get various how-tos, videos, etc.
Where did the British navy end Napoleon's plans to invade Britain?
The British navy end Napoleon's plan to invade Britain at Cape Trafalgar on Oct. 31, 1805, where the French - Spanish fleet under Adm. Pierre de Villeneuve was defeated by Adm. Lord Horatio Nelson.
What is the difference between an Australian compass and British compass?
The needle of a compass must be free to rotate so that it can point to magnetic north. The magnetic field of the earth not only rotates the compass needle horizontally but also pulls one end down. If it pulls the needle down it can stop it from turning freely so on many compasses the needle is balanced for use in a specific zone. There are 5 zones. Austraila and Britain are in different zones. This means the needle may not be level if used in the other's zone. Needles are balanced by making one end of the needle longer or by adding weight to one end of the needle.
Can a compass needle pointing north end you up in the geographical north pole of earth?
no
What direction does the needle of a compass point?
One end points to magnetic north and the other end points to the south.
What does the painted point of a compass always always point North?
The painted end of the compass needle is magnetized. That magnetism is drawn toward the earth's magnetic field, which is to the north.AnswerA compass needle is a tiny magnet, with a north pole and a south pole. These poles are named after the direction in which they point, so the 'painted end' (north) of a compass needle points north because the needle aligns itself with the earth's magnetic field. Magnetic North is the name given to a location, close to True North, whose magnetic polarity is south -which is whyit attracts the north pole of the compass needle.
Which pole of a compass magnet is attracted to Earth's magnetic north pole?
The pole of the compass that is attracted to the earth's magnetic north pole must be a south magnetic pole. But here's the thing. In the compass, the south magnetic pole of the needle is marked "N" because that end of the compass needle points to earth's magnetic north. The only way the needle can point to earth's magnetic north is if that end of the needle, the one marked with an "N" on it, is a magnetic south pole. It almost seems counter intuitive, but think it through and it will become clear.

Why would a hiker carry a magnet and a string?
Using a magnet, string and needle you can create a crude but workable compass. Method Get a needle or a very small nail and a bar magnet. Also get some thread or a bowl of water and two tiny pieces of cork. Hold the needle in one hand and the magnet in the other. Put the North end of the magnet against the needle in the middle and rub it towards and off the point. Lift the magnet up and away from the needle and place it in the middle again. Repeat rubbing the North end of the magnet against one half of the needle 20 times or so. Flip the magnet over so you are using the South end and rub it from the middle to the 'eye' end of the needle 20 times. You have magnetized the needle just like a compass needle. Hanging Compass Tie one end of a length of thread to a stick and the other end to the middle of the needle. Balance is important Let the needle hang freely and slide the thread to a point on the needle where it balances level. Lower the needle into a wide-mouthed jar and lay the stick across the opening to prevent wind interference. Watch which way your compass needle turns. It should always settle to the same direction.
Where would you end up if you followed a compass needle to the north?
To the North Pole.
How can you tell which is the North Pole on a magnet if it is not marked?
A magnet's north pole will attract the south pole of a compass needle (i.e. the end of the needle that points to Magnetic South).
Why a compass is attracted by the north pole but not the south pole?
The compass needle is magnetic so has a north pole and a south pole. North attracts north and south attracts south so the compass needle points to the north pole (you could say it - the other end- points to the south pole too).
Why does a magnet has only N and S directions not E and W?
The needle on a compass points only towards magnetic north. Therefore, the other end of the needle points (obviously) towards the south. East and west can be calculated from the compass without the need for specific pointers.
How does a compass work off of magnetism?
There is a magnetic field surrounding the Earth. The positive pole of this magnetic field (called the north magnetic pole) is near the North Pole. A compass has a freely rotating needle that is magnetized such that one end of the needle points toward the north magnetic pole.
