Chapter 29, Problem 001 A surveyor is using a magnetic compass 6.4 m below a power line in which there is a steady current of 150 A. (a) What is the magnetic field in microteslas at the site of the compass due to the power line? (b) Will this field interfere seriously with the compass reading? The horizontal component of Earth’s magnetic field at the site is 20 µT.
13. A surveyor is using a magnetic compass 6.1 m below a power line in which there is a steady current of 100 A. What is the magnetic field at the site of the compass due to the power line? A)1.6 x10%T B)54x10*T C)3.3x106T D) 62 x10 T 4.8x10 T
A magnetic compass is being used 6.3 m below a power line that has a steady current of 120 A. Will this interfere with the compass readings? The horizontal field of the Earth's magnetic field at this location is 210 ut.
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?
In Oersted's experiment, suppose that the compass was 0.15 m from the current-carrying wire. If a magnetic field of one third the Earth's magnetic field of 5.0×10−5T was required to give a noticeable deflection of the compass needle, what current must the wire have carried? Express your answer using two significant figures.
A horizontal power line carries a current of 5830 A from south to north. Earth's magnetic field (85.2 µT) is directed toward the north and is inclined downward at 72.0° to the horizontal. Find the (a) magnitude and (b) direction of the magnetic force on 120 m of the line due to 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...
A horizontal power line of length 56 m carries a current of 4.6 kA as shown in the figure below. Earth's magnetic field at this location has a magnitude equal to 5.0 X 10-5 T and makes an angle of 59° with the power line. Find the magnitude and direction of the magnetic force on the power line. 13N into the page 13N out of the page 11N into the page 11N out of the page
In a laboratory exercise, you place a compass d=2.50 cm from a wire as shown in the figure below. Using a variable power supply, you slowly increase the current through the wire starting with 1-0. Assume the magnitude of the Earth's magnetic field is 5.0 × 10-5 T and that it points to the right in the figure. (a) If you can detect a deflection of only 3°, what is the minimum current you can detect? (b) Very large currents...
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?
