1. Attraction: The nails of whose and tip of whose staff stuck quick in an attractive field while he fed his flocks."The property of pulling in little bits of iron and steel was alluded to as attraction.
2. NORTH POLE AND SOUTH POLE: If a magnet is suspended unreservedly with the assistance of a string, it generally rests in the north-south direction.The shaft guiding towards north is called north post and the other guiding towards south-shaft.
a) Like posts repulse each other and not at all like shafts pull in each other.
b) It is impractical to partitioned north and south post of a magnet.
c) Poles dependably exits in parts,i.e., attractive mono shafts don't exit.
d) Recent trials have neglected to show proof of attractive mono posts.
e) Two shafts of a magnet are of equivalent quality, and they don't lie precisely at compelling closures and are arranged inwards close to the geometric finishes.
3. The attractive dipole snippet of an attractive dipoles given by , M=m2l .Where m is shaft quality and 2l is dipole minute. S.I. unit of attractive dipole is or J/T.
4. Attractive hub: A line joining north and south posts of an unreservedly suspended magnet is called attractive hub.
5. Attractive MERIDIAN: A vertical plane going through the attractive hub is known as the attractive meridian.
6. COULOMB'S LAW OF FORCE BETWEEN TWO MAGNETIC POLES: As said prior, confined attractive posts don't exit, But the possibility of attractive shaft, however imaginary,is very useful.As will be examined later on, the possibility of attractive dipole is a more palatable origination.
7. Attractive FIELD LINES AND MAGNETIC FLUX: Magnetic field at a point is subsequently said to be one Tesla if a charge of 1 coulomb, while moving opposite to the course of the attractive field with a speed of 1 meter/second, encounters a power of 1 newton.
8. GAUSS'S LAW IN MAGNETISM: The surface basic of the attractive field over a shut surface is zero , i.e.,the net attractive flux through any shut surface is constantly zero.
9. Attractive MOMENT: The dipole minute dipoles in this way numerically equivalent to the torque required to keep the dipole opposite to attractive field of unit impelling.
10. THE EARTH'S MAGNETISM: The branches of material science which manages the investigation of Earth's attractive field is called physical attraction or geomagnetism.
11. The genuine north and south posts lie at the finishes of the polar pivot and are characterized by the hub of turn of he Earth.
12. Attractive ELEMENTS OF EARTH: Those amounts which depict the attractive field of the Earth an a specific pace complete in size and also in heading are known as the attractive components at that place.
13. Attractive DIPOLE AND DIPOLE MOMENT: Two attractive shafts of equivalent and inverse polarities isolated by a little separation frame an attractive dipole.
The attractive dipole snippet of a magneic dipole is a vector m whose extent m is the result of the poe quality (qm) and the separation 2a between the poles.1. Attraction: The nails of whose and tip of whose staff stuck quick in an attractive field while he fed his flocks."The property of drawing in little bits of iron and steel was alluded to as attraction.
2. NORTH POLE AND SOUTH POLE: If a magnet is suspended uninhibitedly with the assistance of a string, it generally rests in the north-south direction.The post guiding towards north is called north shaft and the other directing towards south-shaft.
a) Like shafts repulse each other and not at all like posts pull in each other.
b) It is unrealistic to partitioned north and south post of a magnet.
c) Poles dependably exits in parts,i.e., attractive mono posts don't exit.
d) Recent tests have neglected to show proof of attractive mono posts.
e) Two shafts of a magnet are of equivalent quality, and they don't lie precisely at great closures and are arranged inwards close to the geometric finishes.
3. The attractive dipole snippet of an attractive dipoles given by , M= m 2 l .Where m is shaft quality and 2l is dipole minute. S.I. unit of attractive dipole is or J/T.
4. Attractive hub: A line joining north and south posts of an unreservedly suspended magnet is called attractive pivot.
5. Attractive MERIDIAN: A vertical plane going through the attractive hub is known as the attractive meridian.
6. COULOMB'S LAW OF FORCE BETWEEN TWO MAGNETIC POLES: As said prior, detached attractive shafts don't exit, But the possibility of attractive post, however imaginary,is entirely useful.As will be talked about later on, the possibility of attractive dipole is a more palatable origination.
7. Attractive FIELD LINES AND MAGNETIC FLUX: Magnetic field at a point is along these lines said to be one Tesla if a charge of 1 coulomb, while moving opposite to the heading of the attractive field with a speed of 1 meter/second, encounters a power of 1 newton.
8. GAUSS'S LAW IN MAGNETISM: The surface vital of the attractive field over a shut surface is zero , i.e.,the net attractive flux through any shut surface is constantly zero.
9. Attractive MOMENT: The dipole minute dipoles hence numerically equivalent to the torque required to keep the dipole opposite to attractive field of unit instigation.
10. THE EARTH'S MAGNETISM: The branches of material science which manages the investigation of Earth's attractive field is called physical attraction or geomagnetism.
11. The genuine north and south posts lie at the finishes of the polar hub and are characterized by the hub of revolution of he Earth.
12. Attractive ELEMENTS OF EARTH: Those amounts which depict the attractive field of the Earth an a specific pace complete in greatness and in addition in bearing are known as the attractive components at that place.
13. Attractive DIPOLE AND DIPOLE MOMENT: Two attractive posts of equivalent and inverse polarities isolated by a little separation shape an attractive dipole.
The attractive dipole snippet of an attractive dipole is a vector m whose greatness m is the result of the quality (qm) and the separation 2a between the shafts.
