A drawing pin (British English) is known as a thumb tackor a push pin in American English. Other nails for a drawing pin come from the materials that they are made from, such as, brass tack, tin tack, and iron tack.
Yes, a North Pole of a magnet will repel a drawing pin if the pin is made of a ferromagnetic material, such as iron, because the magnetic field of the North Pole will induce a south pole in the pin. However, if the drawing pin is not magnetic or made from a non-ferromagnetic material, it will not be affected by the magnet at all. In most cases, drawing pins are not magnetized, so they would not be repelled by the North Pole.
Yes, a drawing pin is a conductor. Conductors are materials that allow electric current to flow through them easily due to the presence of free electrons. In the case of a drawing pin, the metal material allows electricity to flow through it.
Drawing Pin
So that they are easy to push into a drawing board.
If you use the larger side of the push pin, you are spreading the force out, therefore making the pressure lower. However, if you use the smaller part of the push pin, the force is concentrated on one spot, making the pressure much, much higher, because if a you apply force on a smaller surface area, you get a larger pressure.
They are the same thing.
Safety pins are a special type of pins, they include a mechanism that consists of a spring and a clasp. They are mainly used to fasten pieces of clothing together. They were invented by American mechanic Walter Hunt. The mass of the average safety pin is about 10 grams.
