The modern paper clip was patented by Gem Manufacturing Company in the 19th century, with the most commonly recognized design attributed to Norwegian inventor Johan Vaaler in 1899. While various forms of paper fasteners existed before, Vaaler's design was notable for its simplicity and effectiveness in holding sheets of paper together without damaging them. The invention aimed to provide a practical solution for organizing documents in an efficient manner.

Paper clips are not permeable in the traditional sense, as they are made of metal and do not allow substances to pass through them easily. Permeability typically refers to the ability of a material to allow liquids or gases to pass through it. Paper clips are solid and do not have pores or openings for substances to permeate through.

it depends. not all clips are made of stainless steel. Many clips nowadays are made from plastic and many different composite materials.
The paper clip was not discovered. It was invented.

The original paper clip was invented by Samuel Fay in 1867. It was called a Ticket Fastener. The modern paper clip was designed in 1899 by William D. Middlebrook. He sold his patent to Cushman and Denison and they called it GEM.
Yes, magnets attract paper clips because paper clips are made of a magnetic material like iron. The magnetic field produced by the magnet causes the paper clips to be attracted to it.
It is not possible to give an exact number of paper clips in 1 mole since mole is a unit used for counting atoms or molecules, not larger objects like paper clips. However, 1 mole of paper clips would contain Avogadro's number (6.022 x 10^23) of individual paper clips.

10 paper clips is 7.5 inches, so 7.5X100,000= A million paper clips
Yes, both metal paper clips and plastic paper clips are mixtures. Metal paper clips are made of metals like steel, while plastic paper clips are made of polymers like polypropylene. Both of these materials are composed of multiple substances mixed together to form the final product.
The number of 1 kg paper clips in a box depends on the size and weight of the paper clips. The weight of individual paper clips vary, so the number of paper clips in a 1 kg box will differ based on the weight of each clip.
The Norwegians used the paper clips as a symbol during the Holocaust.
