Sep 11, 2016. Any magnetic system we shall see has a north pole and a south pole associated with it. The magnetic field originates from the N pole and terminates in the S pole. This two pole system is called a magnetic dipole.11 sept 2016
What is dipole moment in a magnet?
The magnetic dipole moment of an object is readily defined in terms of the torque that the object experiences in a given magnetic field. ... The dipole component of an object's magnetic field is symmetric about the direction of its magnetic dipole moment, and decreases as the inverse cube of the distance from the object.
What dipole means?
1a : a pair of equal and opposite electric charges or magnetic poles of opposite sign separated especially by a small distance. b : a body or system (such as a molecule) having such charges or poles.
What is dipole property of magnet?
magnetic dipole, generally a tiny magnet of microscopic to subatomic dimensions, equivalent to a flow of electric charge around a loop. Electrons circulating around atomic nuclei, electrons spinning on their axes, and rotating positively charged atomic nuclei all are magnetic dipoles.
Is a magnet a dipole or monopole?
As implied by its name, the magnetic monopole consists of a single pole, as opposed to the dipole, which is comprised of two magnetic poles. ... Dirac proposed that the existence of even a single magnetic monopole in the universe would explain why electric charge comes only in multiples of the electron charge.
Is a dipole a magnet?
A dipole magnet is the simplest type of magnet. It has two poles, one north and one south. Its magnetic field lines form simple closed loops which emerge from the north pole, re-enter at the south pole, then pass through the body of the magnet. The simplest example of a dipole magnet is a bar magnet.
Why is a magnet called dipole?
Aritra G. Any magnetic system we shall see has a north pole and a south pole associated with it. The magnetic field originates from the N pole and terminates in the S pole. This two pole system is called a magnetic dipole.11 sept 2016
