From the information given, what you've made is called a "solenoid." Basically a coil of wire wrapped around a core, usually of iron, or some other sort of magnetic material. The more coils, the stronger the electromagnet will become, and thus the stronger the magnetic force. The mathematical formula for finding the strength of the induced magnetic field (B) is,
B = uonI
In other words, the strength of the magnetic field (and thereby magnetic force) is directly proportional to the current and number of loops.

Can an electromagnet lift metal at a water depth of 300 feet?
The magnet on the surface and the metal 300 ft down - no. Lowering the magnet to the metal, then lifting - yes.
What is a force that wraps around a magnet?
magnetic pull
If you are given some iron fillings and a magnet describe how you would find the poles of the magnet?
If possible cover the magnet with a sheet of paper and gently sprinkle the iron filings over the sheet ot paper, they will stick in a pattern following the magnetic "lines of flux" which will get closer and closer near the poles of the magnet. Afterwards you can cleanup by lifting the sheet of paper off of the magnet and the filings will fall away. Without the paper the filings will usually become tightly stuck to the magnet, making it hard to clean.
Will steel nails that are joined by a magnet remain joined if the magnet is removed?
In general, steel nails will not remain "joined" if a magnet touching them is removed. It is important to note that nails affected by a magnet retain a weak "impression" of the field and remain slightly magnetic. But the magnetic field "impressed" on the nails will be quite small and will not hold the nails together once the magnetic is removed.
Why would a bar magnet pick up more paper clips than an eletromagnet?
?? lol i dont know what electro magnets u have been using! if it is a homemade electro magnet, try increasing the coils in the wire ro the power u are putting into it. does the bar magnet (permanent magnet) have a larger surface area than the electro one? also, you do know that the magnetic potential of electro and permanent magnets vary right? they use electro magnets in junk yards that are capable of lifting scrap cars with eaaase
What is a lifting magnet?
A lifting magnet is an electromagnet that is meant to hold or move material that comes in contact with the magnet. This is the opposite of a traction magnet.
How do you test the lifting strength of an electromagnet Such as how many pounds can a specific magnet lift. How to test magnet strength in the field.?
the magnetic field of a magnet is measured through Gaussmeters.
Electro magnet used for?
A electro magnet is used for lifting things by the magnetic force provided by the amount of coils and the size of the battery
What is better for lifting heavy metal objects eletromagnet or permanet magnet?
permanet object
What is a shape of a magnet field?
Depends on the shape of the magnet, but in general, the field is spheroid around the pole of the magnet.
Can an electromagnet lift metal at a water depth of 300 feet?
The magnet on the surface and the metal 300 ft down - no. Lowering the magnet to the metal, then lifting - yes.
Can a magnet affect the circumference?
In general, no.
What should I know before buying magnetic sweepers?
Lifting power versus lifting distance is a primary concern. Also consider the wipe off factor. Then magnet size.
What is converse statement?
Statement: All birds lay eggs. Converse: All animals that lay eggs are birds. Statement is true but the converse statement is not true. Statement: If line A is perpendicular to line B and also to line C, then line B is parallel to line C. Converse: If line A is perpendicular to line B and line B is parallel to line C, then line A is also perpendicular to line C. Statement is true and also converse of statement is true. Statement: If a solid bar A attracts a non-magnet B, then A must be a magnet. Converse: If a magnet A attracts a solid bar B, then B must be non-magnet. Statement is true but converse is not true (oppposite poles of magnets attract).
How do lifting machines work using electromagnets?
They work by changing the location of the magnetism. Another way to think of it is by getting a magnet and having a paper clip follow it the paper clip is the platform being used in lifting. In a lifting machine the platform follows where the magnetism is which is what lifts it.
How do you use one magnet to make a second magnet?
You can magnetize a piece of steel or iron, by stroking it with one end of a magnet. Stroke in one direction only, lifting off and away between each stroke. This aligns the atoms in a regular direction, in the blank piece of steel.
What is the space around a magnet where the forces of the magnet act?
The space around a magnet where the force of the magnet can act is the space occupied by the magnetic field. Alternatively we say that the magnetic field acts in the space around a magnet. That is a very qualitative statement with little predictive value. More predictive value is contained in a statement that the strength of the magnetic field at any position in the vicinity of a magnet is measured by the torque which is exerted on a small magnet moment (compass) place in the vicinity of a magnet. This, recorded with the direction the test compass points is actually a mapping of the magnetic field of a magnet. As a side note, if carefully measured one discovers that strength of the field around a magnet decreases as the inverse cube of the distance when far from the magnet. The field is mostly in the volume near the magnet but the weakening field continues to exist at all distances from the magnet.
