The strength of an electromagnet depends on the current through the coil and
the 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 information
before we can decide which one is stronger.

What will increase the strength of a copper electromagnet?
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
What is the nail in an electromagnet?
The nail in an electromagnet is the core of the electromagnet. It is there to provide the magnetic lines of force a "highway" to get from one end of the coil to the other end through the middle of the coil. The magnetic lines of force "like" the nail because it is a ferromagnetic material. They can travel through it very easily - and they do! The nail also provides the "working end" of the electromagnet. The magnetic field lines emerge from the nail, and then act on what is there. If you are, say, doing a separation experiment removing steel tacks that are mixed in with small brass nails (brads), the tacks will stick to the end of the nail at the "working surface" or the pole of the electromagnet.
Wooden core electromagnet vs iron core electromagnet?
A coil of wire or a coil in the shape of a cylinder is a typical shape for an electromagnet. The strength of the magnetic field of an electromagnet can be increased significantly if the coil is wrapped around an iron core. This does not happen with nonmagnetic materials such as wood or aluminum or rubber. The enhancement of the electromagnet is caused by the magnetic properties of iron. The atoms of iron have magnetic properties as a consequence of thier electronic structure. (The cause of magnetism at the atomic level is a complex issue if described in detail and that complexity is beyond this explanation.) In a simplified picture one can say that at the atomic level the iron atoms act like little magnets. The magnetic characteristics of iron are such that an external magnetic field causes the rearrangement of the electronic structure of the iron at the atomic level and that creates a magnetization in the iron. That magnetizations has its own magnetic field just like a normal permanent magnet. The field created by the magnetization of the material adds to the external field and one gets a stronger magnetic field in and around the iron core.
What are two advantages of a electro magnet over natural magnet?
A permanent magnet is always on; there isn't any way to turn it off. An electromagnet can be controlled; you can turn it on or off, or change the amount of magnetism by varying the current passing through the coils.
What happen to a electromagnet if you switch the current off?
When we turn of the current in an electromagnet then electromagnet looses its magnetic property,provided the material used inside the current carrying solenoid is soft iron core. If, the material is steel then after the current is turned the magnetism propety still prevails and hence steel becomes a permanent magnet.
Why is electromagnet to stronger than electromagnets one and three?
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.
Is an electromagnet made of a coiled wire and a metal bolt stronger than one made with a wire alone?
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.
What will increasing the electric current to an electromagnet do to its magnetism?
An increasing electric current moving into an electromagnet will become stronger in its magnetism. As the atoms align the increasing magnetism will stop at one point, making the electromagnet as strong as it can be.

From where can one purchase a Fiat Coupe 20V Turbo?
One can purchase a Fiat Coupe 20V Turbo in the official Fiat company store or website. In addition, used car companies might sell this specific model of Fiat.
Is a electro magnet stronger than a normal magnet?
it depends on how strong the electromagnet is. you basically choose how powerful to make an electromagnet when your designing one. one used for picking up cars at a junk yard is gonna be more powerful than one used in a kitchen appliance. and "normal magnet's" is not a good term for all other types of magnets. there are lots of different types of materials that can be magnetized, all of them are stronger or weaker then the others, all of them can also be made to different strengths, and all of them lose strength over time. the usefulness of an electromagnet is that they can be turned on and off depending on whether or not they have electricity running through them. http://en.wikipedia.org/wiki/Magnet
What are the advantages of Permanent magnet over Electromagnet?
Unlike a permanent magnet, an electromagnet can be turned on and off. One useful advantage of this: Place a metal bar inside the electromagnet, apply current through the electromagnet in one direction, and the magnetic field would move that bar one way -- reverse the current reverses the magnetic field and the bar would move the opposite way. You could use that effect and make an electronically controlled lock for a door.
What is one electromagnet?
