The following diagram shows two straight wires carrying current. Copy the diagram and draw the pattern of lines of force around them and mark their directions.

(N/A) According to the right-hand thumb rule,when current flows through a straight wire,the magnetic field lines form concentric circles around the wire.
Since both wires carry current in the same downward direction,the magnetic field lines around each wire will be in the clockwise direction.
As the lines of force from both wires interact,they form a combined pattern where the lines between the wires cancel each other out to some extent,resulting in the pattern shown in the figure below.
