What is magnetic effect of electric current?
In when an electric current is allowed to flow through a current-carrying conductor, it can generate a magnetic field. The experiment with a magnetic needle that can show deflection can help to understand this. The deflection will be bigger as the current flow increases. When the direction of this current changes, so does the direction of the deflection.
