Find the magnitude of the magnetic field produced by it at a distance of 2m. 7 A straight current-carrying conductor is carrying a current of 5A. Find the magnitude of the magnetic field produced by it at a distance of 1m. 8 A straight current-carrying conductor produces a magnetic field of 5T at a distance of 2m. Find the magnitude of the electric current flowing through it. 9 A straight current-carrying conductor is carrying a current of 10A and another conductor parallel to it carries a current of 5A on the opposite side as shown in the figure below. Find the magnitude of the magnetic field produced by the system at a distance of 2m. 10 Does the Earth’s Magnetic field varies at different locations?
