In Oersted's experiment, suppose that the compass was 0.25 m from the current-carrying wire. If a magnetic field of half 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?

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.

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)

elaborate on this quote. Does this mean that if I place a
compass above the wire, the NORTH end of the compass will point
towards the wire? like this?
If so, can we imagine the wire as being the virtual magnet,
where the "top" of the wire simulates a north pole and the "bottom"
of the wire simulates a south pole? Why would this be? Is it
because the field lines go from the north end of the magnet to...

You are doing a study of bird migration and need to determine the strength and direction of the Farth's magnetic field B using a magnetometer (a device for measuring magnetic fields). This magnetometer consists of a long wire carrying 10.0 A of current. Assume the wire and the magnetic field are both parallel to the ground. For the two orientations of the wire shown (viewed from above), the magnitude of the force per unit length F/L is given. The orientation...

For this station, you have two coils of wire (each with different numbers of loops), a magnet, some connecting wires, and a galvanometer. A galvanometer is an ammeter that measures very small currents (micro-amperes) and indicates the direction of that current. Understanding how the meter behaves is important here, because you’re going to use the meter to determine/measure current—including its direction. For this galvanometer, when (conventional) current enters the terminal on the right (as viewed when reading the dial), the...
