1. Electromagnetic Field

3. Electromagnetic Field
What is field?
What is land field?
What is an electric field?
What is Magnetic field?

4. Permanent Magnets
S N S N
What happened when two magnets are get closer as bellow
They attract each other
How one magnet attract other with out having physical conduct

5. Permanent Magnets
S N
What happened when two magnets are get closer as bellow
They repel each other
How one magnet repel other with out having physical conduct
N S
Physically they are not touch, but some other way they have a conduct
Through which they get the conduct ?
The answer is ‘ Magnetic Field ’
This magnetic field is not visible our eye

6. • What is magnetic field
The region around a magnet , in which magnetic forces are present
Magnetic field is a force field.
Force is a vector.
So magnetic field is a vector field.
Line of force is flux lines
Flux lines are outwards from North pole and inward to south pole

7. N S
N N
Unlike Poles attracts
Like poles repulse

8. +
Field line(Flux line) due to single
positive charge
Field line(Flux line) due to single
negative charge
-
Magnet will create the magnet field
Similarly electric charge will create an electric field

9. Two Equal and Opposite Charges
They attract each other

10. Two Equal and like Charges
They repels each other
