Answer
True
Explanation
Just as described in the example, whenever electrical current flows, a magnetic field is produced. This principle is stated explicitly in Ampere's Law, wich is part of Maxwell's equations, which are foundational concepts in the science of electromagnetism. Practical applications abound where this principle can be observed and harnessed; in electric motors, generators, transformers and inductors to name a few. Therefore, it can be stated unequivocally that whenever electrical current is flowing, a magnetic field will be produced.
