Yes, there is evidence to support this statement. It is based on the fundamental principle of electromagnetism, which states that opposite charges attract and like charges repel. Electric currents are essentially the movement of charged particles, so this principle applies to them as well.
One example is the behavior of two parallel wires carrying electric currents in the same direction. The wires will experience an attractive force towards each other. However, if the currents are flowing in opposite directions, the wires will experience a repulsive force.
The concept of like currents attracting and unlike currents repelling also applies to magnets. Similar to electric currents, magnets have poles that can be thought of as having positive and negative charges. Like poles (north-north or south-south) will repel each other, while unlike poles (north-south or south-north) will attract.
No, there are some cases where like currents may not attract and unlike currents may not repel. This can occur when the currents are in a complex or dynamic system, where other factors such as magnetic fields or external forces come into play.
Understanding the behavior of like currents and unlike currents is crucial in understanding the fundamental principles of electricity and electromagnetism. It allows us to predict and explain the behavior of electric and magnetic fields, and how they interact with each other and with charged particles.
