What are material required (easily available and cheap) and procedure to make a magnetic field like earth's core does on a bigger scale. I WANT TO SIMULATE OUR PLANET'S MAGNETIC FIELD BY DEFLECTING A COMPASS . I WANT TO SIMULATE THAT OUR PLANET'S SPIN DOES SO BY SPINNING OUR PLANET'S CORE .

Dear student,

Such questions are made for enhancing the self creative skills and should be tried answering on your own. However, here are a few points that will help you in framing your answer:

Our earth possesses magnetic field of its own which is known as earth's magnetic field.Our Earth acts like very large magnet whose north pole is in South (geographic) and south pole is in North (geographic).

We know that like poles of magnet always repel and unlike poles always attract each other.  Now, as unlike pole always attract each other, the compass always points toward north and south direction, with its north pole pointing towards North. 

You may feel free to contact us if you face any issue or difficulty while composing your answer. You can also send us your answers here for a feedback and required corrections, if any.

Regards

Mu metal is a nickel–iron soft magnetic alloy with very high permeability suitable for shielding sensitive electronic equipment against static or low frequency magnetic fields. It has several compositions. One such composition is approximately 77%nickel, 16% iron, 5% copper and 2% chromium or molybdenum
