What would the direction of the magnetic eld at point P be if the current in the wire were reversed? Explain your reasoning. c. What would happen to the magnetic eld at point P if the current in the wire were increased? Explain your reasoning. d. What would happen to the magnec eld at P if point P were farther away from the wire? Explain your reasoning
