Two current carrying wires cross at right angles as indicated in the figure.
If the wires are not restrained, what statement best describes the motion of the wires?
Hint: To help you visualize the situation, draw first the magnetic field that Wire 1 makes at the points shown on Wire 2. Use those magnetic fields and the current of Wire 2 to find the forces on Wire 2. Repeat the same procedure for the magnetic field that Wire 2 makes at the points shown on Wire 1. Use this now to find the forces on Wire 2.
Wire 1 moves out of the page; Wire 2 moves into the page
Wire 1 rotates clockwise; Wire 2 rotates counterclockwise
Wire 1 rotates counterclockwise; Wire 2 rotates clockwise
Wire 1 moves up; Wire 2 moves to the left
Wire 1 moves down; Wire 2 moves to the right
wire 1 has a horizontal current to the left, wire 2 has a vertical current pointing up
Using RHR i got
Wire 1 rotates clockwise; Wire 2 rotates counterclockwise
thats wat i got as well but is that correct
i am not sure. :(
ya that's correct
thanks
To determine the motion of the wires, we need to consider the interaction between the magnetic fields created by the current in each wire and the forces experienced by the wires.
To start, let's consider Wire 1 and its magnetic field at the points shown on Wire 2. Using the right-hand rule, if Wire 1 is carrying current out of the page, the magnetic field created by Wire 1 at the points on Wire 2 will be into the page.
Now, let's determine the force experienced by Wire 2 due to the magnetic field created by Wire 1. According to the right-hand rule for current-carrying wires, if Wire 2 is carrying current in the direction indicated in the figure, and the magnetic field is into the page, the force on Wire 2 will be to the left.
Next, let's consider Wire 2 and its magnetic field at the points shown on Wire 1. Since Wire 2 is carrying current into the page, the magnetic field created by Wire 2 at the points on Wire 1 will be out of the page.
Now, let's determine the force experienced by Wire 1 due to the magnetic field created by Wire 2. According to the right-hand rule, if Wire 1 is carrying current out of the page and the magnetic field created by Wire 2 is out of the page, the force on Wire 1 will be to the right.
Combining these forces, we find that Wire 1 experiences a force to the right, and Wire 2 experiences a force to the left. Therefore, the correct statement describing the motion of the wires is:
Wire 1 moves to the right; Wire 2 moves to the left.
