If we consider a wire in which current is flowing and two charged particles (One is at rest and another one is in motion) magnetic field only present on moving one. Why ?

Dear student,

Magnetic field is caused due to varaition in motion...

hi

if a charge is at rest then only electric feild exists around it. if a charge is moving then there is change in electric feild say at a

point which results in changing magnettic feild . thus a force acts on it given by F=Bqvsinthita. where F is net force on charge ,

B is magnetic feild and v isvelocity of chage q ,thita being the angle at a fixed point on the conductor.

please approve if you like.
