1whenever we say of current we always talk , of conventional current only no ? thus it's the proton beam only no ? thus , They'd attract no?
Two parallel proton beams are moving in same directions.Will they attract or repel each other ??

1they will attract surely think as twoo wire ll & 'i' in same direction attracted but some more data must be available as if an exception is there is Fe>Fb but generally Fb>Fe but not always
110 charge because a wire is neutral in charge as it contains both electrons and protons
1They will repel as only the repulsive forces are dominant in this case.
Whereas, 2 wires carrying current in the same direction attract as the magnetic forces become dominant here.
9aragorn in current carrying wires theres no electrostatic attraction due to 0 charge
1If speed is less than light , Magnetic force will be less than Electric force ..so repulsion..If speed is equal to light ...no force.
1Hehe nice discussions :D , apparently all of u have got it ..
All i meant was they will attract or repel depending on the speed at which they travel..
Magnetic force will be attractive as two parallel wires carrying current in same direction attract each other.
Electrostatic force will be repulsive as like charges repel each other.
If the forces are equal we should have
(1/4πεo)e2/d2 = μoe2v2/2πd2
v = 1/√(ε0μo) = c
If they move with speed of light , then no attraction or repulsion.
Remember magnetic field produced by a moving charge (e , v) is
(μ0/4π)(ev/r2)
1but i have a feeling that they would not do anything
it seems wierd when you think of proton beams attracting or repelling each other
see they're two beams of light
hmmmm maybe .
but anyway since my first answer is the one which i can reason for; i stick to it
and yes guys that is why it is in Satya's Corner after all
1same as electron beams no ?? both in same direction , attract . different directions repel.
right???
11Yes. Instead of a current of electrons, consider a current of protons. Won't they have the same effect?
11What do you think about philip's theory, people? I think he's spot on. [4]
1bcoz there is a current flowing in both cases
i gave it a guess.plz dont take it too seriously
btw what do you think
1yes that s why i think they shud attract each other
its just a guess as you know i waiting for the real answer
11Doesn't that defenition have something to with two current carrying wires attracting each other?
11Can anyone explain why they should attract? Is this bcos, if the initial velocity is high enough, the electrostatic force becomes a nuclear force once the distance between them becomes <106m?
11I didn't get the quesiton, Satya. Can u post some sort of a diagram? I would've immediately said "repel" . But I'm thinking twice bcos this question is under Satya's Corner[4]
