An infinitely long wire is placed near a square loop as shown in the figure.
Which of the following statements is/are true?
1
The mutual inductance between the wire and loop is \(\frac{{{\mu _0}a}}{{2\pi }}\ln \left( 2 \right)\)
2
The mutual inductance between the wire and loop is \(\frac{{{\mu _0}a}}{{4\pi }}\ln \left( 2 \right)\)
3
If a constant current is passed in the straight wire in an upward direction and the loop is brought close to the wire then the induced current in the loop is clockwise.
4
The induced current in the loop is anticlockwise
