True or false any material that exerts magnetic force is considered a magnet?
It is true that materials that exert magnetic forces are considered magnets. This is the case since it shows they have magnetic field lines that may have been induced or were naturally present in the materials.
What is true of any ferromagnetic materials?
It has an abnormally high magnetic permeability, it has a definite saturation point, and it has appreciable residual magnetism and hysteresis. That's why it remains magnetic even after the forcing magnetic field goes away.
True or false the magnetic poles are not located exactly at the geographic poles?
True. The magnetic poles move constantly.
Does the earth spin on its true poles or magnetic poles?
Magnetic poles
Is magnetic north equal to true north at any time during the year?
No. However, "magnetic north" is equal to true north for certain PLACES. The magnetic north pole is a slowly-wandering point which is currently in northern Canada. A line drawn from the north pole to the magnetic north pole, when extended through the rest of the world, defines a line of zero "magnetic variation", the amount by which magnetic north differs from true north. Most navigational maps are overprinted with lines of equal magnetic variation, and a navigator who neglects to properly apply the magnetic variation will become quickly lost.
Is the following sentence true or false most materials have weak magnetic property's?
Yes most materials have weak magnetic properties

Meter in music can be described as what?
The grouping of pulses
True or false When most materials cool they get a little smaller?
It is a true statement.
What do you mean by true course in navigation?
you can travel Magnetic or true courses ie magnetic north and true north. Magnetic north is by way of compass
What material blocks a magnetic field?
There are no materials that STOP magnetic fields. Some have proposed that a faraday cage will stop magnetic fields, but this is not true because magnetism is a field, not a wave. The most effective way to block a magnetic field is to put a bunch of space between it and whatever's in trouble. Ideally, you could encase a magnet in a large plexiglass bubble to keep distance.
What is magnetic variation?
Since the Earth's magnetic poles are not located at the geographic poles, a magnetic compass doesn't point to 'true' (geographic) north. The DIFFERENCE angle between magnetic north and true north is the magnetic variation or declination where you are. It changes for different locations.
