Ampere's law (qualitative)

         

A current of \( i \) flows through a straight wire \( a, \) and a current of \( 2i \) flows through another straight wire \( b \) which is \( 2d \) away from \( a ,\) as shown in the above figure. Which of the following is an appropriate comparison of the magnitudes of the magnetic field strengths at the three points \(A, B\) and \(C?\)

A solenoid has current flow \( I ,\) as shown in the above figure. What is the direction of the magnetic field at point \( A? \)
