Question

A long, straight wire carrying a current I₁ is placed on a horizontal table in front of you and the direction of the current points +x axis. The magnetic field produced by the current I₁ at a point 5 cm above the wire is 0.2 T. A second parallel wire carrying a current I₂ = 3I₁ is placed 10 cm above the first wire and the direction of the current also points +x axis. What is the direction of the net magnetic field produced these two currents at a point 5 cm above the table?

Group of answer choices

out of page (table)

clockwise

counterclockwise

to the right

away from you

into the page (table)n

toward to you

to the left

Answer 1

(2) - es com im (1) - B (magnetic field) at P due to wire = out of page B (magnetic field) at p due to wirea = into the poge Since Current is greater in wire 2, where as distance to point pis same from both the wires, i wire 2 dominates at point P. =) Net magnetic field at point p - points in to the plane (table)
