A horizontal compass is placed 17 cm due south from a straight vertical wire carrying a 46 A current downward. In what direction does the compass needle point at this location? Assume the horizontal component of the Earth's field at this point is 0.45 x 10-4 T and the magnetic declination is 00. 48. X。(counterclockwise from east is positive)
Enumerate two sources of magnetic field Describe how a compass is used to determine the direction of magnetic field Discuss how a moving charge is affected by presence of magnetic field Describe the force experienced by a current-carrying wire in the presence of magnetic field
A freely pivoting bar magnet (such as a compass needle) is placed in a magnetic field created by other sources. True or False: The figure correctly shows the alignment of the compass in the external magnetic field. True False

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 compass is placed 21 cm due south from a straight vertical wire carrying a 35 A current downward. In what direction does the compass needle point at this location? Assume the horizontal component of the Earth's field at this point is 0.45 ✕ 10-4 T and the magnetic declination is 0°. Calculate degree and specify direction.
(9) A straight wire is placed in a uniform magnetic field; the wire makes an angle of θ with the magnetic field. The wire carries a current i, and the magnetic field strength is T. Calculate the force on a segment of length l of this wire. Show the direction of the force in a sketch, which also indicates the direction of the field and the magnetic field. [20 pts]
9. A current carrying wire is placed in the uniform magnetic field as shown in the figure for problem! The magnetic force on the wire is pointing to the left 19) The magnetic field is pointing a) out of the page b) to the left 20) If the current in the wire decreases by a factor of two, the force a) increases by a b) decreases by a c) decreases by a factor of two d) into the page c)...
A compass needle points 21 ∘ E of N outdoors. However, when it is placed 13.0 cm to the east of a vertical wire inside a building, it points 35 ∘ E of N. The Earth's field is the same at both positions of the compass, it is 0.50×10−4T and is horizontal. What is the magnitude of the current in the wire?
