Q
Q: If two parallel wires carry currents in the same direction, what is the interaction between the magnetic fields they produce?
Solution: Two parallel wires carrying currents in the same direction will attract each other due to the magnetic fields they produce.
Steps: 5
Step 1: Understand that when an 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 a current, they will each create their own magnetic field.
Step 3: Determine the direction of the magnetic fields produced by each wire. Use the right-hand rule: point your thumb in the direction of the current, and your fingers will curl in the direction of the magnetic field.
Step 4: Since both wires carry current in the same direction, their magnetic fields will interact with each other.
Step 5: Analyze the interaction: the magnetic field of one wire will exert a force on the other wire, causing them to attract each other.
