EXTRA : MAGNETIC FIELD & ELECTROMAGNETIC INDUCTION1.Consider two long and parallel conducting wires separated by a distance d andcarryingcurrent I. sketch a resultant magnetic field diagram around the axis of thewire for following condition.a)Direction of both the current same.b)Direction of both the current is opposite with each other2.Two parallel straight wires are separated at a distance of 0.75 m between each other asshown inFIGURE 19.2.The first wire carries current, I1=25 A while the second wire carries current, I2= 35 A.if the length of the wire is 2.5 m, determine the magnitude and the direction of themagnetic field at the midway between the two wires when the direction of current isthea)Sameb)Opposite3.FIGURE 19.5shows the end view of four conducting wires. Current flows through the wiresas shown. CopyFIGURE 19.5and sketch the resultant magnetic field pattern which formsaround the wires.4.0.75 m2.5 mFIGURE 19.2FIGURE 19.5I1I10 cmQFIGURE 19.82
FIGURE 19.8shows two parallel wires which carries current I1= 10 A and I2= 8 Arespectively in the opposite direction which is separated at 10cm.a)Determine the position of the point along the line that connects both wireswith zero resultant magnetic field.b)If point Q is at 10 cm from the wire that carries current I2.
