Which best describes search north magnetic pole?
In our solar system has magnetic pole reversal
What terms best describes the space surrounding a magnet in which the magnetic forces acts.?
Magnetic field
What is the difference in the direction of the magnetic field produced around conductor by dc flow and ac flow?
The direction and amplitude of the magnetic field around a wire depend on the direction and amplitude of the current through the wire. When the wire carries DC, the direction and amplitude of the current in the wire are constant, so the direction and amplitude of the magnetic field around the wire are constant. When the wire carries AC, the direction of the current in the wire is periodically reversing and its amplitude typically changes, so the direction of the magnetic field around the wire is periodically reversing and its amplitude is typically changing.
What is used as evidence for sea-floor spreading-?
The rocks on either side of a mid-ocean ridge record the direction of the Earth's magnetic field at the time they were formed, and form a pattern of 'magnetic stripes' on either side of the ridge which are symmetrical. It is also now possible to measure ocean widths with sufficient accuracy to show yearly changes.
How do you know that magnets haven't always point north?
When igneous (born from lava) rocks cool, the iron in them points to the magnetic north pole. By examining these patterns in layers of rock, we can see that these patterns have gradually changed over time. This field of study is called PaleoMagnetism. The magnetic poles can also flip, reversing the north and south directions relatively quickly. These are also recorded in the rock.
Name two deviceswhich use currentcarrying conductor and magnetic field?
Electric motor and loud speakers are the two devices that uses current carrying conductor and magnetic field.
What statements describes electromagnetism?
Magnetism can cause electrons to flow, and electricity can make a wire magnetic.
How magnetic trains stop?
By reversing the polarity of the magnets and there are also friction brakes.
How can you reverse the direction of the magnetic field in a wire produced by an electric current?
You can reverse the direction of the magnetic field by reversing the direction of the electrical current.

Did reversing the direction of the electricity in the wire change the way compasses were affected?
Yes. If a current is reversed, the magnetic field is reversed as well.
What word describes a magnetic field being blocked?
Shielding
