What magnetic pole is at that location? Why?

9. The figure below shows two crossed wires that are carrying currents (I1 = 77.0 A and I2 = 20.0 A ). What is the magnitude of the total magnetic field at point (P) where a = 15.0 cm and b = 5.60 cm? 0of19 oof19 oof9 0of19 oom P oof19 0of19 oon9 oof19 oof oofot oof19 0of19 o

9. A electron with charge -1.60 × 10-19 C and mass 9.11 × 10-31 kg is accelerated from rest through 14.20 kV. It then enters a uniform magnetic field of 7.50 x 10-4 T that is oriented perpendicular to its direction of motion. (a) What is the radius of the path the electron follows in the magnetic field? (b) How long does it take the electron to make one complete circle in the magnetic field?
