NCERT solutions for CBSE and other state boards is a key requirement for students. Doubtnut helps with homework, doubts and solutions to all the questions. It has helped students get under AIR 100 in NEET & IIT JEE. Get PDF and video solutions of IIT-JEE Mains & Advanced previous year pap...
As previously mentioned, they generate a magnetic field. More specifically, magnetic sheet fanners induce a magnetic field of equal polarity onto the steel sheets that require separation. With the same polarity, a repelling force is created. When run through a magnetic sheet fanner, the steel ...
The scientific study of matter's characteristics and behaviour is known as chemistry. Chemistry vocabulary and Chemistry glossary are different from the normal vocabulary. It is a branch of natural science that examines the building blocks of matter, including the atoms, molecules, and ions that mak...
What is a hard drive? A hard drive, also known as a hard disk drive (HDD), is a storage device used on many computer devices. It stores all of your digital data using magnetic fields. Your documents, photos, videos, music, applications, programs, and the operating system represent digita...
Figure 1. The polarity of current flow in the conductor is determined by the application of the right-hand rule for generators. The amount of electromagnetic induction in a conductor is determined by the number of coil turns (loops), the strength of the magnetic field, relative motion speed,...
What is the basic principle of the magnetic compass?()Magnetic materials of the same polarity repel each other and those of opposite polarity attract The Earth's magnetic lines of force are parallel to the surface of the Earth Magnetic meridians connect points of equal magnetic variation The comp...
Rub the object on the end of the magnet to make it magnetized with the polarity(极性) of that end. The earth has magnetic field, so the ends of the object are drawn to the earth's magnetic field. And then the compass points north....
