They attract each other
How one magnet attract 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

• 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

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
