B) repel each other
C) do not affect each other
D) effect depends on the material of wire
Correct Answer: B
Solution :
The crosses in the figure denote that the direction of magnetic field is perpendicular to the page away from reader. Now lets take case of wire one. Magnetic field at wire (1) due to wire (2), i.e., vertically downwards, into the page current in wire (1) is flowing upwards. So, force acts to left side i.e., it is repulsive. Similarly, on wire (2) it is one right side. Directions of magnetic fields are opposite so both wires will repel each other.You need to login to perform this action.
