The needle clamp is collar and screw device that holds the needle to the needle bar. The needle bar is the part that goes up and down as the machine sews and is in front of the pressed foot bar.
The device that turns a needle in a galvanometer is called a coil or a solenoid. It generates a magnetic field when current passes through it, causing the needle to deflect in response to the current being measured.
The device that turns a needle in a galvanometer is called a coil. The coil generates a magnetic field when current flows through it, which interacts with the magnetic field produced by the permanent magnet in the galvanometer to cause the needle to deflect.
The advantages of a needle valve include good flow control and the ability to allow high pressure ratings. The disadvantage is the higher risk of clogging because of the entrained solids.

The device you are describing sounds like a compass. The magnetized needle aligns with the magnetic field of the Earth, allowing users to determine their direction relative to the north.
I've never heard of anyone using a curved needle for any kind of piercing. But, a straight needle would be much easier for a tragus. A lot of force has to be used to pierce the tragus and that would be difficult with a curved needle. Also, I could imagine that the curved needle would hit the cartilage/ear behind your tragus after it was pierced. Just get it done with a straight one.
A mounted needle is a very thin, sharp needle that is mounted or attached to a handle or rod for various medical or laboratory procedures, such as injections, blood drawing, or specimen collection. The handle provides stability and control for precise and safe usage of the needle.
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.
