Question pad ....is it possible that magnetic field is zero.........koi jaruri thodi na hai ki hamesha koi field ho.....0 bhi ho sakta hai

Not quite. If a particle moves in a straight line through a region of space, that means the net force on it is zero. If we assume that all nonmagnetic forces on the particle are already known to be zero, that means that the magnetic force is also zero: [math]f_B = q \vec{v} \times \vec{B} = 0.[/math] This does not imply that the magnetic field is zero, but rather only that the component of the magnetic field perpendicular to the charged particle's velocity is zero. In other words, the magnetic field, if it exists, is parallel to the particle velocity.

,when electron move parallel or antiparallel to magnetic field then it remains undeflected.

Undeflected motion me koi force ke na hona possible hota hai......par force hai ye bolne ke liya aur information chahiye...
