An electromagnet attracts paper clips when current is applied, creating a magnetic field. The electromagnet loses them when current and magnetic field are removed. An electromagnet is a type of magnet in which the magnetic field is produced by an electric current. [17] The magnetic field disappears when the current is turned off.
A bulldog clip Another picture of a bulldog clip. A bulldog clip is a device for temporarily but firmly binding sheets of paper together. It consists of a rectangular sheet of springy steel curved into a cylinder, with two flat steel strips inserted to form combined handles and jaws.
Paper Clips is a 2004 American documentary film written and produced by Joe Fab, and directed by Fab and Elliot Berlin, about the Paper Clips Project, in which a middle school class tries to collect 6 million paper clips to represent the 6 million Jews killed by the Nazis during World War II.
Paramagnetic materials have a weak induced magnetization in a magnetic field, which disappears when the magnetic field is removed. Ferromagnetic and ferrimagnetic materials have strong magnetization in a magnetic field, and can be magnetized to have magnetization in the absence of an external field, becoming a permanent magnet. Magnetization is ...
The Paper Clips Project, by middle school students from the small southeastern Tennessee town of Whitwell, created a monument for the Holocaust victims of Nazi Germany. It started in 1998 as a simple 8th-grade project to study other cultures, and then evolved into one gaining worldwide attention.
Magnetic levitation can be stabilised using different techniques; here rotation (spin) is used. Magnetic levitation (maglev) or magnetic suspension is a method by which an object is suspended with no support other than magnetic fields. Magnetic force is used to counteract the effects of the gravitational force and any other forces. [2]
Wawa and a police carThis guy gave new meaning to the slogan “Gottahava Wawa.” Police in East Windsor, N.J., arrested a 24-year-old man on Dec. 23, and charged him with...
Magnetic media also deteriorates naturally with typical shelf lives between 10 and 20 years. [7] Magnetic tape can degrade from binder hydrolysis or magnetic remanence decay. Binder hydrolysis, also known as sticky-shed syndrome, refers to the breakdown of binder, or glue, that holds the magnetic particles to the polyester base of the tape ...
