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

• 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 linesFlux lines are outwards from North pole and inward to south pole

Unlike Poles attracts

Like poles repulse

+

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

Two Equal and Opposite Charges

They attract each other

Two Equal and like Charges

They repels each other
