A power line carries a 500-A current towards magnetic north and is suspended 10 m above the ground. The horizontal component of earth’s magnetic field at the power line’s latitude is 24 T. If a magnetic compass is placed on the ground directly below the power line which direction will it point? In this question, I understand why how to use both of the equations but could you explain why the direction is 22.62 degrees west of north in detail?

a horizontal power line carries a current of 5000 A from south to North. A horizontal magnetic field of magnitude 2 T has direction from east to west. what is the magnetic force on 2-m long power line? give magnitude and direction.
A high-voltage power line carries a current of 134 A at a location where the Earth's magnetic field has a magnitude of 0.59 G and points to the north, 66 ∘ below the horizontal. Part B Find the magnitude of the magnetic force exerted on a 260 m length of wire if the current in the wire flows horizontally toward the east.
1- A power line carries a current of 81A west along the tops of 8.5-m-high poles. a) How does this compare with the Earth's magnetic field of about 12 G? b) here would the wire's magnetic field cancel the Earth's field?
A horizontal power line of length 52.2 m carries a current of 1.98 kA northward as shown in the figure below. The Earth's magnetic field at this location has a magnitude of 4.60 x 10-5 T. The field at this location is directed toward the north at an angle 65.0° below the power line. B 65.0° (a) Find the magnitude of the magnetic force on the power line. N (b) Find the direction of the magnetic force on the power...
an overhead electric power line carries a maximum current of 250 A. what is the magnitude of the maximum magnetic field in telsa at a point 0.037 m directly below the power line?
4. A high-voltage transmission line with a resistance of 0.31.2/km carries a current of 1000 A. The line is at a potential of 700kV at the power station and carries the current to a city located 160 km from the station. What is the power loss due to resistance in the line? b) What fraction of the transmitted power does this loss represent?
An overhead electric power line carries a maximum current of 125 A. What is the magnitude of the maximum magnetic field at a point 4.50 m directly below the power line? Ans: 5.6 x 10-6T
A typical overhead power line is bare wire at a high potential relative to ground. A local line receives power at 3300 V with respect to the ground; the delivered voltage is slightly less, due to resistance loss in the wire. The wire is 10 km long, carries a current of 60 A, and has a resistance (made small to limit power loss) of 2.5 Ω. 1) Approximately how much power is lost due to the resistance of the wire?...
