Electromagnetic force on parallel wires

This equipment shows the electromagnetic force acting on two parallel current carrying wires. When the currents are in the same direction, there is an attraction force between the two wires. When the currents are in the opposite direction, there is a repulsion force between the two wires. The force is caused by the interaction of the circular magnetic field produced by each wire.

What apparatus do we need for making this experiment

Good job, man.  Thanks for posting this.

strange, if you have two electrons stationary, they repel each other (static force), but if you take these same two electrons and shoot them down a parallel path, they then attract each other (two parallel line currents in same direction). 

if two static electrons are placed north and south on the earth, shouldn't the electrons attract each other since the are both travelling parallel due to the direction of the earth's rotation (parallel line currents) ?

One doubt, if the current flow continously in a time interval, any problem?

It's a good demonstration, but why do half a job? Tell all the other details too Please.

How many Volts and Current are you running through that to get it to respond like that?

It will help to know a practical knowledge

Hey seriously it works...i thought its restricted oly to d buk....:-P
