Blanket Stitch Characteristics:
1. Edge Finishing: Blanket stitch is often used to finish the edges of fabric, preventing fraying.
2. Even Stitches: The stitches are evenly spaced and form a uniform line along the edge of the fabric.
3. Versatile: It can be used for both functional and decorative purposes in various embroidery designs.
Steps for Blanket Stitch:
1. Step 1: Begin by inserting the needle at the edge of the fabric and pulling it through.
2. Step 2: Insert the needle again at the same spot, but keep the thread looped over the edge.
3. Step 3: Pull the needle through the fabric, creating a loop that lies along the edge.
4. Step 4: Repeat the process along the edge, ensuring the stitches are uniform in size.
Draw the pattern of the magnetic field lines for the two parallel straight conductors carrying current of same magnitude 'I' in opposite directions as shown. Show the direction of magnetic field at a point O which is equidistant from the two conductors. (Consider that the conductors are inserted normal to the plane of a rectangular cardboard.)
