Detailed Solution

The above statement is True.
A wire that carries current acts like a magnet. A magnetic field with closed lines will form around a wire carrying an electric current. Current-carrying conductors behave as magnets as long as an electric current passes through them. These magnets, which show magnetic properties only when current passes through them, are called electromagnets. Magnetic field lines can be identified using the Right-Hand Thumb Rule. The figure shows that the direction of current decides the direction of magnetic field lines.
