Q:Just for the convenience of using magnets on a surface, or is it actually practical in some other way to use a magnetic material?: Arbitrary. It's just that sheet steel is the cheapest commonly available material with the necessary properties (rigidity, humidity resistance, formability, longevity). Same reason a lot of other things are made from steel (cars, dishwashers, computer cases).

Q:How can I protect a device from magnetic field?: Shield it with a metal covering.

Q:what is meant by this ‘cold roll grain orientation‘?: I think it reduces hysteresis and maybe increases relative permeability. What gives a magnetic material the ability to concentrate a magnetic field is all the tiny, movable magnetic domains within the material lining up along with the applied field, and adding to it. Some of the domains can get stuck after the field is removed, causing hysteresis(residual magnetization). And the degree to which this happens depends on the mircostructure of the metal. Most metals, unless they're made specifically to be single crystal which is difficult and expensive, are made up of billions or microscopic pieces of pure crystal separated by impurities in the metal. These little crystals are called grains. And the impurities between grains, grain boundaries. The number of domains that are available to move(this is what determines a materials permeability) also depends somewhat on the microstructure of the metal. Atoms act differently at grain boundaries than they do within the grain. And the orientation of the crystal within the grain makes a difference as well. The way a metal is worked changes the grain structure, maybe from short fat grains to long thin grains, fore eample. And crystals with random orientations to more organized orientations.

Q:1. Satellite ground operators use the feedback from a device called magnetometer, which senses the direction of Earth‘s magnetic field, to decide which torque coil to activate. what direction will the magnetometer read for earth‘s magnetic field whrn the satellite passes over earth‘s equator.2. In order to protect other equipment, the body of a satellite must remain unmagnetized, even when the torque coils have been activated. Would hard or soft magnetic materials be best for building the rest of the satellite?: If you have to ask.go invest $75 in an oil pump, and draw the oil out through the dipstick. Life is too short to risk your neck to a flimsy jack.

Q:Are the Permeability and Magnetic susceptibility same ?: No. Magnetic susceptibility is a measure of how much a material is magnetized in response to an external magnetic field whereas permeability expresses the total magnetization of an entire volume of a material.

Q:If a product contains Fe, it can be attracted by a magnet. But not to attract other metals. Then this product does not have magnetic pressure: Magnetite: can be attracted by magnets. Iron oxide is not magnetic. Most of the magnetic materials are iron compounds, which is correct because the magnets are mostly mixtures.

Q:can magnetic force pass through magnetic material?: maybe you can get 4 more tires put the spare back in the trunk then you will be safe for a while

Q:I need a simple yet sophisticated meaning of a magnetic field for Homework /:: Iron (Fe) is a transition metal in group 8, period 4.

Q:What are the differences between magnetic materials and conductive materials?: Magnectic Materials are materials that do attracts other metals and creats there own magnetic fields, while conductive materials are one of which allows the flow of electricity through them

Q:Also, who came up with refrigerator magnets?: Sorry for misunderstanduing your question. To answer your additional details clarification, no, it doesn't have to be made of a ferrous material. the refridgerator container could be made from purely styrofoam if you wanted it to be. That's just a container.
