Introduction When an electric current flows through a straight copper wire, it generates a magnetic field that forms circular patterns around the wire. The Biot-Savart law is a relation that allows us to calculate the strength of this magnetic field at different distances from the wire. And its applications aren’t limited to straight wires. For […]
Introduction Everything in the universe exerts an attractive force on matter around it, which is where the concept of gravitational force comes in. Gravity is one of the four fundamental forces of nature, with the other three being strong nuclear force, weak nuclear force, and the electromagnetic force. Strong nuclear force is a very short […]
Introduction Electric charge is an intrinsic property of matter that allows it to experience a force when placed in an electric field. Charges are classified into two types or signs: positive, and negative. You can create a simple charged object by rubbing a balloon against your hair, which transfers charges from one body to another. […]
Introduction In simple terms, force is just a way for two objects to interact. Its effect is that of a push or pull and it causes a change in the position and/or velocity of the object it is being applied on. The application of force also lends us the possibility of doing work as the […]
Introduction The concept of pressure plays an integral role in our daily activities. For instance, a knife edge exerts a large amount of pressure on fruits and vegetables. While the science behind it may be new for some people, this occurs because the edge of the knife is very sharp. Surfaces that have small areas […]
Introduction A plane slanted at a particular angle is known as an inclined plane. Such a plane is connected to the ground on one end while the other end is raised by a given height that is referred to as the slant height. The angle of inclination for an inclined plane is defined as that […]
Introduction A wave is defined as the propagation of a continuous disturbance across two points. They can propagate with, or without a medium in between the given points and on this basis, they are broadly classified as follows: Mechanical waves: A wave that requires a medium to propagate. For sound waves cannot travel in vacuum. […]
Introduction In 1820, Hans Oersted conducted a famous experiment using a compass needle and a current-carrying conductor. He observed that when no current was flowing through the conductor placed near the compass, the latter would always point towards the north pole. However, when the conductor was carrying a current, the needle deflected in a particular […]
Introduction The Ampere is one of the seven fundamental units, which include metre, kilogram, second, Kelvin, mole, and Candela. It is used to measure the flow of electric current and is abbreviated as A or amp. Different systems of units like KGS, CGS, and International SI use different units for current and other basic quantities, […]
