A straight current carrying conductor is kept along the axis of circular loop carrying current. The force exerted by the straight conductor on the loop is
1 Perpendicular to the plane of the loop
2 In the plane of the loop, away from the center
3 In the plane of the loop, towards the center
4 Zero

In the given figure, the loop is fixed but straight wire can move. The straight wire will
1 remain stationary
2 move towards the loop
3 move away from the loop
4 rotates about the axis
Explanation:
If we consider a small element \(d L\) (shown in figure), the magnetic force on the considered element is towards the straight wire. Thus, the wire move toward the loop.

In the figure current \(I\) flows in a circular loop and straight wire. The loop is fixed butstraight wire can move. The straight wire will
1 Remains stationary
2 Move towards the loop
3 Move away from the loop
4 Rotate about the axis
Explanation:
By Fleming's left hand rule, force by the small element of circular loop is towards the wire. So, they attract each other hence move towards the loop.

An infinitely long, straight conductor \(A B\) is fixed and a current is passed through it. Another movable straight wire \(C D\) of finite length and carrying current is held perpendicular to it and released. Neglect weight of the wire
1 The rod \(CD\) will move downward parallel to itself
2 The rod \(CD\) will move upwards parallel to itself
3 The rod \(CD\) will move upward and turn anti-clock wise at the same time
4 The rod \(CD\) will move upward and turn clockwise at the same time
Explanation:
Since the force on the rod \(CD\) is non-uniform it will experience force and torque. From the left hand side it can be seen that the force will be upward and torque is clockwise.
