What will be the reaction for current flowing in a wire ?

Although some might think that this Q of mine is an inclination towards amateurism

but yet this is what i want to know :)

if every action has an equal and opposite reaction, then what will be the reaction for current flowing in a wire ?

When Newton's 3rd law talks about 'action/reaction' it is referring to forces between bodies. If body A exerts a force on body B, then body B exerts an equal and opposite force on body A. One of those forces is the 'action'; the other is the 'reaction'. (It doesn't matter which is which.)

'Action/reaction' is sort of old fashioned terminology. Nowadays we speak of '3rd law pairs'.

There is resistance to current flow. The EMF forces the charges (electrons) to flow, and the 'resistance' opposed the current.

Big transformers in substations are designed for the turns to move as a reaction from the large magnetic fields produced by the surge current when switching in a big load.

Well i totally have consent to your post, but Mr. Newton proposed that the reaction should be equvalent to the action.
Thats what giving me a thought, the equivalence to the flow?
Which i could not think of?

Probably i could find some one ellaborating that

so what's up

any one here can solve the issue!

Current flowing in a wire is the 'reaction' to a potential difference 'action' between two points.

Point A has a surplus of charge, and Point B has a deficit of charge, hence there is a difference in the potential energy. Current, otherwise known as dQ/dt or the movement of charge over a period of time, is a description of how the charged particles move from A to B, limited only in magnitude by the resistance of the medium.

Reading into Conservation of energy, Ohm's Law and Kirchhoff Voltage/Current Laws should give you answers also.

well every thing work alright uptill it is in concern to opposition, but i can't work out about the equivalence of the two pair?

confused !
