Magnetism
Property of a substance/object ———— allows it to produce magnetic field and produce/respond magnetic effect (attraction/repulsion)
Causes/origin of magnestism
Motion of charged particles (electrons) and charges
1.When valence shells are partially filled
2.The atoms vibrate/carry current in same direction
Domain theory of magnestism
If atoms carry current in same direction,they are magnetized
Domain
Set of atoms carrying current having North pole on same direction
Magnetism of an atom
Caused mainly by the orbital motion of electrons
Same poles
Repel
Magnetic field
The area around magnet in which it produces a force on another magnetic object
Magnetic field
The area around magnet in which it produces a force on another magnetic object
Magnetic field path
Inside—————S to N
Outside ————N to S
Magnetized object
Atoms carry current in same direction
