What is a magnetic compass?
A magnetic compass has a needle mounted in a way that allows it to turn freely. Tis needle always lines up with Earth's magnetic field and points toward magnetic north. The needle is set over a diagram that shows east,south, and west. By knowing which way is north, a sailor can find the other diections.

Why does stroking a needle with a magnet make it magnetic?
Stroking a needle with a magnet aligns the magnetic domains in the needle material in the same direction, causing the needle to become magnetized. This alignment of domains creates a magnetic field in the needle, giving it magnetic properties.
To use a needle and cotton?
Thread the cotton through the eye of the needle, leaving a tail to hold onto. Hold the needle steady and start sewing by pushing the needle in and out of the fabric. Remember to knot the thread at the end to secure your stitches.
What is flame byxis's special move?
it is destiny needle, and magnetic needle storm. :)
What is a magnetized needle that is attracted to the Earth's North magnetic pole?
It is still a needle, but could be referred to as a compass needle.
What is mounted needle used for in science?
A mounted needle is used in science for tasks such as sample preparation, microinjection, and manipulation of small objects. It allows for precise and controlled handling of samples under a microscope or other instruments.
Why is a mounted needle used when preparing microscope slides?
A mounted needle is used when preparing microscope slides to handle small specimens or sections with precision. It allows the user to position and manipulate the specimen without touching it directly, which helps prevent damage and contamination. Additionally, using a mounted needle can help ensure that the specimen is evenly dispersed and properly positioned on the slide for observation.
Why a strip of mirror is mounted under the needle and near the scale of a voltmeter How this may help to rreduce errors while taking a reading?
The strip of mirror is mounted to help eliminate parallax errors when reading the value on the scale of the voltmeter. By aligning the needle's reflection with its actual position on the scale in the mirror, the observer can avoid viewing the needle from an angle, which could result in an inaccurate reading due to parallax. This setup ensures a more precise and accurate reading of the voltmeter.
What material is a compass made from?
A compass is typically made from a magnetized needle mounted on a pivot. The needle is often made of magnetized steel or other ferrous material that can align itself with the Earth's magnetic field. The housing of the compass may be made from materials such as plastic or metal.

How does a magnetized needle work?
The magnetic field of earth exerts a torque on the needle, pulling one end or pole of the needle toward the Earth's North magnetic pole, and the other toward the South magnetic. The needle is mounted on a low-friction pivot point, in better magnetized needle a jewel bearing, so it can turn easily. When the magnetized needle is held level, the needle turns until, after a few seconds to allow oscillations to die out, one end points toward the North magnetic pole.
What is the difference between a hypertonic needle and a hypotonic needle?
A hypotonic needle is a needle that is a non coring needle. A hypertonic needle is a coring needle. Both of these needles are used in IV's with a hypotonic needle used for hypotonic solutions.
What is a teasing needle?

You should lower a coverslip using a mounted?
To lower a coverslip onto a mounted slide, hold the coverslip at a slight angle above the specimen then gently lower it to let the mounting medium spread evenly and minimize air bubbles. Avoid pressing down too hard to prevent squashing the specimen or damaging the slide.
What is a swagged needle?
