there aren't any, so there isn't any.

No because the Moon does not have a magnetic field like the Earth does. The Earth's magnetic field appears to be created by a liquid metalic out core circulating around a solid core. This works like a dynamo which creates the magnetic field around the Earth. The Moon lacks a similar core stucture. This is also the reason why the Monn has no atmosphere.A magnetic compass would not work on the moon, for the moon does not have the magnetic field that the earth has, allowing us to use this device.No, because moon does not have magnetic force like earth
Magnetic reluctance is a concept used in the analysis of magnetic circuits. The term was coined in May 1888. There are several methods to determine the magnetic characteristics.
It is overloaded. take the motor loose and see if it runs normally if its on a machine that used to work check bearings misalignment bent shafts
in mines
The red needle points to magnetic north and the white points to magnetic south. The bearings tell what direction the next point is.
yes
One is magnetic bearings where there is little or no contact from the rotating shaft. Also magnetic levitation, as used in high speed trains.
a magnetic compass shows the direction of magnetic north and bearings from ita compass is also a drawing utensil in design and technology that you can use to draw accurate circles. This has been improved by Harriet webster

When sailing a course magnetic bearings are used. However there is a difference between magnetic north and true north called the magnetic variation, this changes year by year and can be a very significant figure depending on your position. It is important therefore to know this to ascertain ones true course.
Your question is very vague...is it how to remove bearings or how the replace bearings or how to size new bearings on an old worn shaft???? And what bearings??? There are several hundred bearings on a car...one kind of bearing on fishing reel...for or five bearings on a bicycle
Usually tapered roller bearings.
not sure ...
magnetic forces are used in magnetic poles
