The strength of an electromagnet is determined by the number of windings, the current flowing through the windings, and the permeability of the core.
An electromagnet typically has a stronger magnetic field than a solenoid. This is because an electromagnet uses a ferromagnetic core, such as iron, to enhance its magnetic strength, while a solenoid is simply a coil of wire without a core.
An electromagnet has a stronger magnetic field than a solenoid because an electromagnet has a core material (such as iron) that enhances its magnetic strength by aligning and concentrating the magnetic field lines. In contrast, a solenoid is simply a coil of wire without a core, and it produces a magnetic field by running an electric current through it.
A solenoid is a coiled wire with an electric current running through it, causing a magnetic field. An electromagnet is almost the same thing except it is much stronger than a solenoid (usually) and, unlike a solenoid, has a soft, iron core.
An electromagnet is a stronger magnet.

A bolt is typically a stronger electromagnet than a nail because of its iron content and shape that allows for better magnetic alignment. The increased surface area and mass of a bolt result in stronger magnetic properties compared to a nail.
Yes. An Iron core electromagnet has a stronger magnetic field then a coil. The magnetic flux is condensed and travels through the iron core with little resistance, while air provides much greater resistance.
Electromagnet two is stronger than electromagnets one and three because it generally has a greater number of coil turns and a larger current flowing through its wire, resulting in a stronger magnetic field being produced. Additionally, the core material used in electromagnet two may be better suited for enhancing the magnetic field strength compared to the cores used in electromagnets one and three.
The strength of an electromagnet depends on the current through the coil andthe number of turns in the coil. The voltage across the coil doesn't matter at all.So IF both of your electromagnets have the same number of turns in their coils,then the one with 20A of current is stronger than the one with 5A of current.If they have different numbers of turns in their coils, then we need more informationbefore we can decide which one is stronger.
There's no set answer to that. The strength of the solenoid isn't decided by the voltage alone, so it'd be entirely possible to build them either way.

An electromagnet is typically stronger than a permanent magnet because it can be adjusted by changing the electric current flowing through it. Permanent magnets have a fixed magnetic strength that cannot be easily altered.
