Question

Problem 3: (10 points) Two long wires are oriented so that they are perpendicular to each other. At their closest, they are 20.0 cm apart. What is the magnitude of the magnetic field at a point P between them if the top one carries a current of 18.0 A to the left and the bottom one carries 12.0 A to the right? IT = 18.0 A 12.0 cm B = ? P 8.0 cm 1b = 12.0 A Bottom wire

Answer 1

Given Wire out the top one carries Curret Ing = 18A Curret at bottom wire WIB IB = 12 A from top wire the point pris distance a Magnetic field a = 12cm at IT 1262 8cm at the up and by top wire is given IB 3 4x1077 10 x 48 By = ll. It 24 a 3x10-5 T By Qk x 12 x 102. 6 By out of the plane at the bottom top at point P. and point 'Plis at distance 8cm from Bottom wire wire of

.7 x BB = BB 2K a Magnetic field at the pähts by Bottom wire is a la q lla JB 46x10 x 22 26 8x102 Bo T this magnetic field is also out out of plane at point ? total magnetic field at P 3x105 the . due to both coires, B = Brt BB Shop B = 3x10.5 +3x10s 6x10ST B
