Q
Q: Two parallel wires carry currents I₁ and I₂ in the same direction. What is the nature of the force between them?
Solution:
Parallel currents attract each other due to the magnetic fields they create.
Steps: 5
Show Steps
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 carrying currents, each wire creates its own magnetic field.
Step 3: Note that if the currents in both wires are in the same direction, the magnetic fields interact with each other.
Step 4: Learn that the interaction of these magnetic fields causes a force between the two wires.
Step 5: Conclude that since the currents are in the same direction, the force between the two wires is attractive.
