What is fossil magnetism?
In hot Iron bearing rocks or magmas the iron minerals they contain align themselves parallel to the Earth's magnetic field. When they cool below about 500 degrees Celsius the the iron minerals 'freeze' in this magnetic orientation and are no longer able to adapt to any changes in the Earth's field (which occasionally reverses polarity and wanders). This frozen magnetic alignment is a fossil of the ancient magnetic field and can be 'read' to find out what the Earth's magnetic field has been doing in the past.
What is the working principle of Magnetic stirrer?
A magnetic stirrer is helpful for dissolving solids in liquids. As there are several different appearances, all of them will at least have a base with a speed-controlled spinning magnet inside and an exterior stirring bar. You place the stirring bar into a flask or beaker by tenderly sliding it beside the wall of the container. To avert fracture, don't drop the bar onto the bottom of the container. Place the container on the stirrer base and turn the speed control knob to its lowest set. Use enough speed to start the bar turning in the container. If using exact volumes, as with a volumetric flask, be sure take the measurements before adding the stirring bar.When stirring is finished, keep the stirring bar in the container by draft the liquid into another container. Carefully wash the original container and the stirring bar.
