| + | Calculate the magnetic potential difference V_m for the following paths as shown by the solid lines. \\ | ||
| + | Dotted lines are only for there for symmetry aspects! \\ \\ | ||
| + | The wires conduct the following currents: | ||
| + | * $|I_1|=2 ~\rm A$ | ||
| + | * $|I_2|=5 ~\rm A$ | ||
| + | * $|I_3|=11 ~\rm A$ | ||
| + | * $|I_4|=7 ~\rm A$ | ||
| + | Pay attention to the signs of the currents (given by the diagrams) and of the results! | ||

| + | Based on the right-hand rule and the part of a full revolution the following results: | ||
| + | |||
| + | - Task: $+I_1 - I_2 = -3 ~\rm A$ \\ \\ | ||
| + | - Task: $+{{1}\over{4}} I3 = 11/4 ~\rm A$ (it does not matter which way the path goes from the startpoint to the endpoint, as long as it has the same direction and number of revolutions) \\ \\ | ||
| + | - Task: $-{{1}\over{4}} I1 = -0.5 ~\rm A$ \\ \\ | ||
| + | - Task: $+2 \cdot I_2 - 1 \cdot I_3 = -1 ~\rm A$ \\ \\ | ||
