Solution


Q.

Read the passage given below and answer the following questions from (i) to (v).

The magnetic field lines of an infinite wire are circular and centered at the wire and they are identical in every plane perpendicular to the wire as shown in the figure.

Since the field decreases with distance from the wire, the spacing of the field lines must increase correspondingly with distance. The direction of this magnetic field may be found with a second form of the right-hand rule. If you hold the wire with your right hand so that your thumb points along the current, then your fingers wrap around the wire in the same sense as B.

 

(v) A positive charge is moving towards a person. The direction of magnetic field lines will be in:
1 clockwise direction  
2 anticlockwise direction  
3 vertically upward direction  
4 vertically downward direction  

Ans.
