I'm struggling with this doubt. Here it is.... There is a infinitely long current carrying wire. A charged particle is projected with a velocity v parallel to direction of flow of current... then it get deviated due to magnetic force qvB Where q is charge of the particle v is velocity of particle B is field due to wire at the position of particle
But when the same situation is observed in the frame which is moving with same velocity v as that of charged particle there is no magnetic force as velocity of charged particle with respect to that frame is zero....but the particle is deviated from its path... How is this possible?? I read in a book that " what was a pure magnetic field in one frame turns out to be a combination of electric and magnetic field in other frame " I really can't understand this...If it converts into two forces then what is value of each force And I didn't understand why it turns out to be a combination of two forces...it is given in that book that 'electric and magnetic fields are two aspects of Same entity '.... but I didn't clearly why it is so... Please help me with this
