The factors that affect the power of electromagnets are: the current (amperes), the amount of coils, and whether a soft iron core is present. These affect the electromagnet because the current is what provided the electrical energy which created the magnetic field, and so the greater the current, the stronger the magnetic field; the amount of coils is a measure of the resistance provided by the wire, and so the greater that is, the more electrical energy is being used to strengthen the magnetic field; finally, the soft iron core further strengthens the magnetic field as it can be temporarily magnified, so it will become a magnet itself.

How are electromagnets different from magnets?
You can turn electromagnets on and off.
How are electromagnets different from permanent magnet?
You can turn electromagnets on and off.
Where use electromagnets?
Inside of electric motors are electromagnets and permanent magnets. In a metal junk yard large electromagnets are used to pick up metal. In MRI's large electromagnets are used for imaging.
How are electromagnets diffrent to either temporary or pemanent magents?
Electromagnets can be turned on and off.
What is one advantage of using electromagnets instead of permanent magnets?
Electromagnets can be turned off and off
When are electromagnets used to increase or decrease the voltage of electric currents?
Electromagnets are never used to increase or decrease the voltage in a circuit. These magnets in conjunction with a rotating device (an armature) can create a voltage but the do not have any effect on a voltage.
What is the flow of electromagnets called?
Electromagnets
Can Magnets still attract underwater?
Yes, water has almost no effect on magnetic fields. (though electromagnets might have a shortcircut)
How do abiotic factors effect biotic factors?
how does tornados effect abiotic and biotics
What variables affect the behavior of electromagnets?
Primarily the current and the number of turns. Also more subtle factors such as the magnetic properties of the core.
Do electromagnets affect glue?
Electromagnets do not affect glue.
How are electromagnets different from magnets?
You can turn electromagnets on and off.
Do food processors have electromagnets?
Yes, food processors do have electromagnets.
Are all electromagnets magnetic?
All electromagnets are magnetic when they are turned on.
How are electromagnets different from permanent magnet?
You can turn electromagnets on and off.
Factors that effect the oral communication?
There are many factors that effect oral communication. One of these factors is the word choice of the individuals talking.
Where use electromagnets?
Inside of electric motors are electromagnets and permanent magnets. In a metal junk yard large electromagnets are used to pick up metal. In MRI's large electromagnets are used for imaging.
