IT INCLUDES ALL BASIC CONCEPTS DEFINITIONS,PICTURES,EXAMPLES. BETTER TO UNDERSTAND. BEST CONTENT WITH BEST ANIMATIONS AND TRANSITIONS. ALSO INCLUDES EARTH MAGNETIC FIELD DEFINITION OF EARTH MAGNETIC FIELD. IT INCLUDES BEST EXAMPLES AND REAL LIFE EXAMPLES,WHICH CAN HELP TO UNDERSTAND THE WHOLE CONCEPT.

8. The ends of the magnet where
the magnetic force is
concentrated are called magnetic
poles.
Each magnet has 2 poles : North
& South pole.

9. # The Concept of “Magnetic Fields”

10. Every Magnet has at least one North pole and one South pole. By convention,
we say that the magnetic field lines leave the North end of a magnet and enter
the South end of a magnet.
If you take a bar magnet and break it into two pieces, each piece will again
have a North pole and a South pole. If you take one of those pieces and break
it into two, each of the smaller pieces will have a North pole and a South
pole. No matter how small the pieces of the magnet become, each piece will
have a North pole and a South pole.
It has not been shown to be possible to end up with a single North pole or a
single South pole, which is a monopole ("mono" means one or single, thus one
pole).

13. DEFINITIONS CONNECTED WITH EARTH’S
MAGNETISM
 Geographic axis :- The straight line
passing through geographic north and
south poles of earth.
 Magnetic axis :- The straight line
passing through the magnetic north
and south poles of the earth.
Magnetic axis of earth makes
an angle 20 degree with the

14.  Magnetic equator
It is the great circle on the earth perpendicular to the
magnetic axis.
 Magnetic meridian
The vertical plane passing through magnetic axis of a
freely suspended small magnet.
 Geographic meridian
The vertical plane passing through geographic north
and south poles.

16. The shape of
the magnetic
field around a
long, straight
wire carrying
electric current
Looping the
wire turns the
magnetic field
into a toroidal
(donut) shape.
Many loops in a
solenoid shape
creates a dipole-
shaped magnetic
field, similar to that
of a bar magnet
