The astatic needle was invented by John Leslie in 1804. It improved the accuracy and sensitivity of early galvanometers used in scientific experiments.
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.
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.
it is destiny needle, and magnetic needle storm. :)
It is still a needle, but could be referred to as a compass needle.
The needle clamp holds the needle in place on the sewing machine, preventing it from shifting or falling out during sewing. It helps ensure that the needle stays aligned with the machine's mechanisms, allowing for precise stitching.
The astatic needle was created by Leopoldo Nobili in 1825.

Andre-Marie Ampere made original, significant contributions to mathematics and chemistry and is renowned for his new branch of physics - electrodynamics.

Astatic is a term used to describe something that is unstable. As in, astatic; not moving, not static, or stable. "The chemical reaction was astatic, so the professor told us stay away from the experiment table."

The syringe needle was invented in the United States by Charles Pravaz and Alexander Wood in the mid-19th century. They developed the concept of a hollow needle attached to a syringe for medical injections.
The hypodermic needle theory was invented by Harold Lasswell in 1927. He states that Media can 'inject' ideas/behaviours directly into a passive audience or society.
