c) What's μ
Consider a current I = 5 A in a long straight wire along +z-direction as shown in the figure. The dashed line represents a circular closed path of radius r = 11 cm around the straight wire. Closed path with length (L) a) The direction of the magnetic filed at a distance r due to the current I will be: OClockwise (CW) ●Counterclockwise (CCW) b) Using Ampere's law, the equation to calculate the magnetic field at point P is: Hol B 2πT 2xr OB нов Hol OB 2x72 c) The magnitude of the magnetic field B at point P is: B = T = =
