Science > Physics > Magnetism > Magnetic Dipole Moment of a Magnet In this article, we shall study the terminology of a bar magnet and the concept of the magnetic dipole moment of a magnet. Bar Magnet: A bar magnet is a rectangular parallelepiped body which exhibits magnetic properties. When a bar magnet is suspended […]
In this article, we shall introduce ourselves to the Indian Easements Act, 1882. This Act is very important in combination with the Transfer of Property Act. As the name itself suggests it is a mere right enjoyed by a person to utilize other’s property without owning it. Such rights are granted to the person enjoying the right, by […]
Science > Physics > Magnetism > Types of Magnetic Materials In this article, we shall study types of magnetism, types of magnetic material, and Curie temperature. On the basis of magnetic behaviour magnetic materials are classified into three types: diamagnetic, paramagnetic, and ferromagnetic substances. Origin of Magnetism: The origin of magnetism in substances can be […]
Science > Physics > Magnetism > Magnetic Field and Geomagnetism The branch of physics which deals with the study of earth’s magnetic field is called terrestrial magnetism or geomagnetism. The magnetism on the surface of the earth can be approximately represented by assuming a huge imaginary bar magnet in the interior of the earth. The […]
Science > Physics > Magnetism > Magnetic Field and Magnetic Lines of Force In this article, we shall study the concept of a magnetic field, magnetic lines of force, types of magnetic material. When a magnetic needle is kept on a wooden table it comes to rest in the north-south direction. If another magnet is […]
Science > Physics > Magnetism > Magnetization and Demagnetization In this article, we shall study the methods of magnetization, methods of demagnetization and Induced Magnetization. The process of converting iron or its alloys into a magnet is called magnetization. Methods of Magnetization: Single Touch Method: Keep the bar which is to be magnetized on a […]
Science > Physics > Magnetism > Properties of Magnet In this article, we shall see the properties of magnet and experiments to verify them Types of Material: Magnetic Materials: Materials which are attracted by magnets are called magnetic material. e.g. Iron, cobalt, nickel Nonmagnetic Materials: Materials which are not attracted by magnets are called non-magnetic […]
Science > Physics > Magnetism > Magnets About 600 to 800 BC the people living in Magnesia in Asia Minor found a stone (an ore of iron Magnetite Fe2O3) which was capable of attracting iron pieces towards it. They called this stone as magnetite. During the course of time, the name changed to a magnet. […]
Science > Biology > Human Anatomy and Physiology > Cardiovascular System > Disorder Associated With RBCs Anaemia (Anemia) Anaemia or Anemia is defined as a decrease in the ability of the blood to carry oxygen due to (1) a decrease in the total number of erythrocytes, each having a normal quantity of hemoglobin, or (2) […]
Science > Biology > Human Anatomy and Physiology > Cardiovascular System > Composition of Blood: Erythrocytes When a human blood sample is prevented from clotting and spun in a test tube (centrifuged), in a machine called a centrifuge, the blood separates into a straw coloured liquid called plasma and a dark brown mass of blood […]
