PRS Question: Parallel Current Carrying Wires

## PRS: Parallel Wires Consider two parallel current carrying wires

PRS: Parallel Wires

Consider two parallel current carrying wires. With the currents running in the same direction, the wires are

attracted (likes attract?)
repelled (likes repel?)
pushed another direction
not pushed – no net force
I don’t know

## PRS Answer: Parallel Wires I1 creates a field into the page at

7

I1 creates a field into the page at I2. That makes a force on I2 to the left.

I2 creates a field out of the page at I1. That makes a force on I1 to the right.

Answer: 1. The wires are attracted
