Why magnetic field line are uniform.

1.	Why magnetic field line are uniform.
Answer» Ye to pta h ...... but tedha medha kuy nhi nikle skta . Matlb ek magnet bnao , then jo north pole se field line niklega use tedha -medha bnao or south me le jao. When magnetic field lines are parallel then magnetic force experienced by an object is same at all points in that field and such a field is called uniform magnetic field. For example a bar magnet\'s strength is greater at its poles[non uniform] however inside a solenoid the magnetic field lines are parallel.??? Give me reason. Ye thedha medha bhi to ho skta h.
