Q: Two parallel wires carry currents in the same direction. What is the nature of the force between them?
Solution: When two parallel wires carry currents in the same direction, they exert an attractive force on each other due to the magnetic fields they create.
Steps: 6
Step 1: Understand that when electric current flows through a wire, it creates a magnetic field around the wire.
Step 2: Recognize that if you have two parallel wires, each carrying current, they will each create their own magnetic field.
Step 3: Note that the direction of the magnetic field created by each wire depends on the direction of the current flowing through it.
Step 4: Since both wires are carrying current in the same direction, the magnetic fields they create will interact with each other.
Step 5: The interaction of these magnetic fields causes the wires to exert a force on each other.
Step 6: Specifically, when the currents are in the same direction, the force between the two wires is attractive, meaning they pull towards each other.
