Two wires shown in figure p19.48 carry currents of 5.00A in opposite directions and are seperated by 10cm. Find direction and magnitude of the net mag field.
(a) at a point midway between the wires. (b) at point P1 (c) at point P2
B= u0I / 2pir
The Attempt at a Solution
How would i approach a question like this? How does opposite charges affect the sign in the equation B1+B2?
