Problem 3

The purpose of this problem is to find the Net Magnetic Fieldforce of the two electric currents at point P.

There are two parallel wires carrying currents I₁ =15 A and I₂ =25 A, as it is shown in the figure below.The arrow on each wire shows the direction of the current in thewire.

The distance between the two wires is 10 Cm. The distancebetween point P and the wire (I₁ ) on the left is 4Cm.

1 Cm = 10^-2 m

Instruction:

           Solid blue circle indicates the direction of the electric currentis out of the paper

           

         Solid bluecircle with a cross sign indicates the direction of the electriccurrent goes in to the paper.

I₁ = 15.0 A (solid blue)-------------------pX-------------------------------------------------------(solidblue w/cross) I₂ = 25.0

          

                                                                                                                                  

1. Calculate the magnetic field ( B1) of the left wire (I₁ ) at point P. Show your formula and solution belowthis line.

B1 =

1. Calculate the magnetic field ( B2) of the right wire (I₂ ) at point P. Show your formula and solution belowthis line.

B2 =

1. Draw the magnetic field vectors B1 and B2,   at pointP, on the figure.

1. Calculate the net magnitude of the magnetic field , B(Net) andshow the direction of the B(Net) at that point (P).
