It is well known that electromagnetic force depends on frame.
I was reading a book, it says
If a charge is moving parallel to a current carrying wire then a magnetic force will be exerted on charge. But if we start moving with the charge at same velocity then it is in rest for the moving frame but it will experience the force again and since both frames( stationary one and the moving one) has no acceleration w.r.t each other so acceleration on the charge will be same in both frames but reason of this acceleration in moving frame as there is no magnetic field must be an electric field
My question is that it is well known that current carrying wire is neutral so how can there be an electric field in moving frame and if it is there then what is the origin of this field?
As it was marked as a possible duplicate, I want to clarify that I want an intuitive answer. There is written that a moving current carrying wire will appear as charge. How it is possible when wire is neutral? I am new to electrodynamics so sorry if i ask bad questions.
