Two wires carry currents into the page. One carries a 2A current while the other carries a 4 A current. They are positioned at opposite corners of a 10 x 10 cm square as shown below. 10 cm Punivermin, 2020 1=2A 10 cm "1=4A (a) Calculate the magnetic field at point P due to the wire carrying a 2 A current. Be sure to state magnitude and direction. (2 marks) (b) Calculate the magnetic field at point P due to the wire carrying a 4 A current? Be sure to state magnitude and direction. (2 marks) (c) Calculate the net magnetic field at point P, again be sure to indicate the magnitude and direction. (2 marks) (d) If an electron were moving 3 m/s to the right as it passes point P, calculate the electric field necessary to keep the electron from accelerating at this point. Be sure to comment on magnitude and direction of the field. (4 marks)
