O 14 The figure shows five different current sources going either in or out of the screen. I = 3.45 A, 125.21 A, b = 3.26 A and Is 10.2 A. The line integral of the magnetic field moving clockwise around the black circle as shown is 5.23 x 10 6 Tm. What is the direction and magnitude of current 14? A hp A positively charged particle with q = +650 nC is located at the center of circular current loop with diameter d=5cm as shown. The loop has a current that results from the battery and the resistor shown. If the particle velocity is v = 750 m/s up the page as shown, then calculate the magnitude and direction of the magnetic force acting on the particle. 12 V 60 ww , +9 d = 5 cm hp B, C, D The figure shows two very long current carrying wires that do not interfere with each other as shown. The current in the vertical wire moves up the page and the current in the horizontal wire moves towards the right as shown. In which region(s) could the magnetic field be zero? C A B. D hp
