Unformatted text preview: 2 where c is a constant. a) Find the magnetic field at a < r < 3a. b) Find the magnetic field at r > 3a. c) If the magnetic fields produced at points 2a and 4a are B 1 and B 2 , respectively. Find the ratio of B 1 /B 2 . Q: In Figure, the current in the long, straight wire is I 1 = 5 A, and the wire lies in the plane of the rectangular loop, which carries 10 A. The dimensions are c = 0.1 m, a = 0.15 m, and b = 0.45 m. Find the magnitude and direction of the net force exerted on the loop by the magnetic field created by the wire. Q : An ideal solenoid that is 100 cm long has a diameter of 4 cm and a winding of 500 turns and carries a current of 3 A. i) Calculate the magnetic field inside the solenoid. ii) Find the magnetic force acting on the electron moving with velocity v= along the axis of the solenoid Q : Figure shows two long, straight wires carrying currents I 1 and I 2 . What is the net magnetic field at point P, in unit vector notation?...
