Am i right when i say that like currents attract, and unlike currents repel?
In summary, there is evidence to support the statement that like currents attract and unlike currents repel, based on the fundamental principle of electromagnetism. An example of this can be seen in the behavior of parallel wires carrying electric currents in the same or opposite directions. This concept also applies to magnets, where like poles repel and unlike poles attract. However, there are some cases where this statement may not hold true, such as in complex or dynamic systems. Understanding this concept is important in comprehending the fundamentals of electricity and electromagnetism, including how electric and magnetic fields interact with each other and with charged particles.

No one can say whether you are right or not. 
You will have to explain what you mean by like and unlike currents.

Two parallel wires carrying current in the same direction attract each other. Two parallel wires carrying current in opposite directions repel each other.

thank you mrspeedybob, exactly what i was wondering!
1. Is there evidence to support the statement that like currents attract and unlike currents repel?
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.
2. Can you provide an example of how like currents attract and unlike currents repel?
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.
3. How does this concept apply to magnets?
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.
4. Is this statement always true in all situations?
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.
5. How is this concept important in understanding electricity and electromagnetism?
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.
