I cannot remember for sure, but in an electromagnet, an aluminum core would not have any permeability to add to the electromagnet's strength. An electromagnet is more efficient when a thicker core is used; it generates more power. The material you use should be prone to magnetism, as in attracted by permanent magnetic apparatuses or the such. So, an aluminum bar/core (cannot be magnetized), like you stated, wouldn't be the best choice for your magnet's core.
No Scott a non-magnetic collar cannot be magnetized.
Aluminum cannot be magnetized, as it is not magnetic. When aluminum is attempted to be magnetized, the results are poor.
Uranium is a paramagnetic element.
Plutonium is only paramagnetic.
Mercury at normal temperature and pressure is a liquid and will not hold a magnetic field - so it cannot be magnetized.
You cannot magnetize a permanent magnet because it is already magnetized.
Well... the electromagnet has a magnetic field around it which will then attract the paper clips, depending on how much strength the electromagnet has. Also the current flowing in the coil [wires] will make the nail or the electromagnet magnatise.
It will depend on the voltage of the electromagnet. If it does not have enough voltage, then it cannot life 3kg.

Seeds are not metal, therefore they cannot be magnetized, which makes this question is irrelevant.
