A wire of length $L$ is placed parallel to the lines of force in a uniform magnetic field $B$. If $I$ is the current in the wire, then it will experience:
1 a force in the direction of magnetic field
2 a force in the direction opposite to the direction of magnetic field
3 a force in the direction perpendicular to the direction of magnetic field
4 no force
Explanation:
D A wire is placed parallel to the lines of force in a magnetic field and a current flows in wire. Then the wire will not experience any force at all.

A current flows in a conductors from east to west. The direction of the magnetic field at a point above the conductor is :
1 towards east
2 towards west
3 towards north
4 towards south
Explanation:
C By the right hand rule: If the right hand thumb points in the direction of a current the magnetic field at a point will be given by the direction of curl of fingers at that point. Hence in this case as the thumb points from east to west, the fingers at a point above will point in the north direction. Hence, direction of a magnetic field will be towards the north.

Consider two straight parallel conductors $A$ and $B$ separated by a distance $x$ and carrying individuals currents $I_{A}$ and $I_{B}$ respectively. If the two conductors attract each other, it indicates that
1 the two currents are parallel in same direction
2 the two currents are antiparallel in direction
3 the magnetic lines of induction are parallel
4 the magnetic lines of induction are parallel to length of conductors
Explanation:
A When the two conductor are attracting each other that means the two currents are flowing parallel in same direction.
