1. Increase the strength of the magnetic field. (More field lines to be cut by wire, therefore more voltage induced)
2. Move the magnet - or the wire - more quickly. (More field lines cut per second, therefore more voltage induced)
3. More coils in wire. (A single straight wire moved in a magnetic field will cut the lines once, but a coil of wire will cut the lines twice. More coils, more cutting, more induced voltage).

You can increase the prodution of voltage (in a transformer) by increasing the number of turns (changing the turns ratio). If you are attempting to induce a voltage on a wire, placing the wire closer to the source of the magnetic field will increase the magnetic flux, thus increasing the voltage.

An electromagnet gets stronger when you ...
- increase the current (amps) through the wire
- increase the number of turns of wire around the core
- decrease the diameter of the core
- fill the core with a more magnetically permeable material

How can the current on an electromagnet increase?
Yeah buddy - until something smokes. It does, and so does increasing the amp supply but you have to be careful not to melt the wire. Preferably you should increase both. -Good Luck Note; You automatically increase the amps being used by increasing the voltage applied.
How can an electromagnet be made stronger?
An electromagnet can be made stronger by: - A bigger iron rod. - A bigger battery/more batteries - More coils around the iron rod. - A bigger magnet. - Increase the current flowing through the coil. - Put in a soft iron core.
Why electromagnet is different from a permanent magnet because an electromagnet what?
Mainly in that the electromagnet is NOT permanent. In other words, it can be switched on and off.Another relevant difference is that the electromagnet constantly requires power, at least while it is on.
The strength of an electromagnet only depends on the current in the coils?
And the amount of coils.
Is there a magnet in an electromagnet?
An electromagnet is a type of magnet in which the magnetic field is produced by the flow of electric current. The magnetic field disappears when the current ceases. Take a look at this Wikipedia page for more information: http://en.wikipedia.org/wiki/Electromagnet
What happens if you increase the current in an electomagnet?
As current increases, the electromagnet strength will increase.
How could an electromagnet on a crane at a scrapyard be made to pick up heavier cars?
increase the current on the electromagnet
Two ways to increase the strength of an electromagnet?
-- Increase the current (amperes) flowing through the coil of wire that surrounds the electromagnet. -- Increase the number of 'turns' of wire in the coil.
In an electromagnet the magnetic forces increase as increases?
It increases as the current increases.
Inductor works in direct current?
Yes, an inductor works with direct current. It is called an electromagnet. Of course, a practical electromagnet has series resistance, otherwise the current in the inductor would increase to the limit of the current/voltage source.
How can a electromagnet pick up more metal things?
More than what? - An electromagnet can pick up metal due to its magnetism - assuming it is turned on. If you increase the current, the electromagnet becomes more powerful - but you must be careful not to pass too much current, otherwise the wires might burn through.

Why does the strength of the electromagnet increase from the coils?
The electromagnet is made stronger in proportion to the current given. Refer to the link provided for more information.AnswerWhen current passes through the coil of wire surrounding the core of an electromagnet, it acts to align the magnetic domains within that core. Once all the domains have been aligned, the electromagnet has reached 'saturation' and is as strong as it can get. So the strength of an electromagnet is NOT proportional to its magnetising current.
What happens when you decrease the current in an electromagnet?
When you decrease the current in an electromagnet, the magnetic field decreases.
The what of an electromagnet is determined by the direction of current flow?
The electromagnet (polarity) is determined by the direction of current.
How do you make a super power full electromagnet?
-- Use greater length of wire. -- Wind it into more turns around the coil. -- Decrease the diameter of the coil. -- Increase the electrical current through the coil. Each of these actions will increase the strength of the electromagnet.
What is a magnet made by electric current?
An electromagnet.
