Toward which magnetic pole of Earth is the north pole of a compass needle attracted? a. The north pole of a compass needle is attracted to the north magnetic pole of Earth, which is located near the geographic north pole of Earth. b. The north pole of a compass needle is attracted to the south magnetic pole of Earth, which is located near the geographic north pole of Earth. c. The north pole of a compass needle is attracted to...

Two bar magnets are arranged so that they are parallel to each
other. In case 1, north poles face each other on the right side. In
case2, south poles face each other on the right side. In what way
is the resulting field pattern the same, and in what way is it
different?

1-A compass is held horizontally. The silver end of the needle
points towards geographic south and the blue end points towards
geographic north. The compass is then brought near one pole of a
horseshoe magnet. The blue end of the compass points towards this
pole. What is the polarity of this pole on the magnet?

Which of the following about the earth's magnetic properties is true? a. The north pole of the earth's fictitious magnet lies beneath the north geographic pole. b. The earth's magnetic field lines end at the south geographic pole. c. The earth's magnetic field lines originate from the north geographic pole. d. The compass needle points to the earth's north geographic pole. e. The earth's magnetic field lines point to the geographic south.

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...

The magnetic field of Earth resembles the field of a bar magnet. The north pole of a compass needle, used for navigation, generally points toward the geographic north pole. Which magnetic pole of the Earth is the compass needle pointing toward?

A hiker walks in the direction that a compass needle points. In which location would the hiker's direction deviate the most from geographic north? Assume that the compass needle is affected only by earth's magnetic field.

A compass in a magnetic field will line up? a) with the north pole pointing in the direction of the magnetic field. b) with the north pole pointing opposite the direction of the magnetic field. c) with the north pole pointing perpendicular to the magnetic field.
