Yes, having a sewing needle embedded in the foot could be dangerous if you were to have an MRI. The magnetic field of the MRI machine could cause the needle to move or potentially injure the surrounding tissue. It is important to inform your healthcare provider or the MRI technologist if you have a foreign object in your body before undergoing an MRI.
Pressure is inversely related to the area on which force is applied. As the needle has pointed edge the pressure would increase and so it would be easier to go through the cloth for sewing purpose
Rubbing a needle back and forth on a magnet would align the magnetic domains within the needle, causing it to become magnetized. The needle would then exhibit magnetic properties and attract items such as paper clips or iron filings.
A needle can float on water due to surface tension. The surface tension of water is strong enough to support the needle and prevent it from sinking, as long as the needle is carefully placed on the water and doesn't break the surface tension.
The north end of a compass needle would point toward the north pole of a bar magnet.
The magnetic field of the compass may be slightly influenced by the presence of the aluminum bar, but aluminum itself is not magnetic so it won't affect the compass significantly. You would generally need a stronger magnetic field to noticeably affect the compass's needle.

A small sewing travel kit would have several colors of thread and buttons. It of course, would have a needle too.
If you use straight pins to hold the pattern pieces to your fabric, be sure to remove them before sewing because the machine needle might hit one. If this happens, the sewing needle might bend or break and, in either case, the needle would no longer work.
B. needle stitching :)
Sewing machines are used to fasten pieces of fabric together by using needle and thread, just like you would if you were sewing by hand, only much faster and neater.
To operate a sewing machine, you will need a place to set the machine up, thread, bobbins and a needle for your machine and fabric type.
A millinewton. NOT a gram, which a measure of mass, not of weight.
Hand sewing is done by using a needle with thread, and joining two fabrics with the thread. Generally, for hand sewing, you would choose a thread size based on what you're sewing. The higher the wt number, the lighter (or finer) the thread is.
You can but I suggest boiling it first or using a lighter to get all the germs off- also, you need to remember that a sewing needle is super skinny so unless you can find jewelry that's the same size of a sewing needle I wouldn't do it. I pierced my own lip before but it was with an actual piece of ear jewelry so I knew that it would be the gauge I wanted it to be- plus a sewing needle kind of hurts your finger when you're trying to push it through, so I'd also suggest putting an eraser on the end of it so it doesn't stab your finger. Sure you can if you want to get an infection. Boiling it doesn't do you any good. The water allows more bacteria to collect on the needle. Also, it only sanitizes the needle. Professionals use autoclaves which completely sterilize the needle. The sewing needle is way too small to have a comfortable transition between the needle and the jewelry. Fact of the matter is that you are not trained to pierce yourself. DON'T DO IT. Wearing ear jewelry in a lip piercing is a bad idea. The back of the earring will most likely become embedded in your lip. Save up the money to get it done by a pro. Just because some people are lucky enough to not get infections doesn't mean you'll be just as lucky.
You would put your finger under the needle< so u didnt have to stab urself
You can't use a sewing needle to pierce your nose because it might not be the same size as the nose stud and the sewing needle may not be clean enough to use if i were you i would go to a local tattoo shop and get it done because i did it myself and it wasn't pretty.
