what will be happened to the resisitivity if the doped impurities in the non magnetic metal is magnetic ions
Conductivity in metals depends upon presence of unpaired electrons in their valence shell per atom.
If we do the doping of magnetic ions then number of unpaired electron will increase but they are anti parallel to each other so net magnetic moment will decrease so Conductivity will decrease.
Hence Resistivity is Increase.

(a) please write down the resistivity as a function of temperature for a metal. please separate it into four regions such as resistivity is proportional to T, proportional to T^5,proportional to T^2 and proportional to T^0. Please also explain why is that ? (b) what will happened if the doped impurities in the non-magnetic metal is magnetic ions? (c) what is the resistivity as a function of temperature for an instrinsic semiconductor ? (d) how about the resistivity change as...

What would have happened to a calculation of the specific heat of your metal in the second trial if you had not carefully dried the metal before reuse? Clearly explain your reasoning. NG 3 3. What would have been the effect on your calculation of the specific heat of the metal had you forgotten to add the correction for your calorimeter constant? Explain. 4. How would your data have been affected if you had failed to dry your calorimeter between...
A non-magnetic metal ring is suspended from a thread. It is spinning. You bring a strong magnet near the ring but not touching it and the ring stops rotating. What is happening? A. The ring is being repelled by the magnet. B. The ring is being attracted to the magnet. C. The part of the ring approaching the magnet is repelled from the magnet and the part of the ring moving away from the magnet is attracted to the magnet....
