The copper wire has to be wound around a iron core to get the full effect of electromagnetism.
Dynamo has constant magnet inside.When movement comes up ,magnet starts turning .And outside of magnet has coiled wire .So this movement of magnet causes electromagnetic effect .Finally current consists with this electomagnetic effect.
When ever a wire is changed, change it by the same type, rating or capacity of wire.
The shape of the magnet is unimportant. Any moving magnet can induce a voltage in a wire. Or any changing magnetic field. If the magnet rotates, its magnetic field will change, so yes.
Yes. the determining factor is the total amount of current going round. So in a wire with 1 amp current, a magnet with 10 turns of this will have half the strength of 20 turns.

Rea Magnet Wire was created in 1933.
The population of Rea Magnet Wire is 800.
A magnet does not normally stick to silver. However a current of electricity passing through silver wire will produce a magnetic field around the wire. That electric field would have an effect on a magnet, the principle of a solenoid switch. Copper is usually used in such switches as it is cheaper but silver could be used.
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.
One way to increase the strength of a copper electromagnet is by adding another coil. Another way is by wrapping the copper coil around a nail made of iron.Adding more loops to the wireWrapping the copper wire around an iron nailIncreasing the current
By changing the length of wire, say reducing it, the resistance will drop and that will increase current flow but the voltage is less likely to change V=IR.
