Increase voltage. Increase the number of windings,
No, as in this case,the rod is the magnet,and the strength of a magnet does not depend on its size.
welll a scrap heat metal magnet works because it has an electromagnet inside it. The electromagenet has a soft iron core (so that when it can be turned on and off), a coil of wire with lots of turns (to increase the strength of the magnet), and the voltage is very high( also to increase strength.
They are bar magnet ,horse shoe magnet ,lime stone magnet.
Gf
Increase voltage. Increase the number of windings,
Of course that has a great effect since as the magnet strength increase the number of magnetic flux lines increase increasing the induced electromotive force but motion of magnet is needed.

Increase the size of the magnet. Increase the current passing through the wires (electromagnets) Increase the number of coils of the wire (electromagnets)

2 things #1 increase the size of the magnet and the amount of times the wire is wrapped around the rod. #2 decrease the size of the wire and increase the power.
NO!!! the strength of magnet is not affected by temperature
Yes it does!
The strength of a scrap heap magnet vary depending on the strength of the current or number of "turns" in its primary coil. Increasing either or both of these makes the magnet stronger.
No the temperature doesn't the size does.
It will depend on the strength of the magnet. If there is any strength to it at all, there shouldn't be a problem.
the magnetic field of a magnet is measured through Gaussmeters.
