Does the strength of an electromagnet depend on the number of volts passing through the wire or the number of coils of wire wrapped around the iron core?
The strength of an electromagnet depends on: -- The magnitude of the current through the wire. (This depends on the voltage between the ends of the wire.) -- The number of turns of wire in the coil wrapped around the iron core.
What factors control the strength of an electromagnet?
The strength of an electromagnet is determined by the density of coils surrounding the magnet, and the rate of current passing through those coils.
What can affect the strength of an electromagnet?
The power of the battery controlling it.
Does the length of a wire affect the strength of an electromagnet?
longer= stronger
What is the relationship between the stength of an electromagnet and the number of turns in the coil?
As the number of turns in the coil increases, the strength of the electromagnet increases.
Would increasing the length of a rod in an electromagnet increase it's magnetism?
No, as in this case,the rod is the magnet,and the strength of a magnet does not depend on its size.
What does not affect the strength of an electromagnet?
a donut

Does freezing an electromagnet affect the strength of it?
yes
What factors control the strength of an electromagnet?
The strength of an electromagnet is determined by the density of coils surrounding the magnet, and the rate of current passing through those coils.
What does the energy of an electromagnet wave depend on?
Frequency
What are the advantages and disadvantage's of an electromagnet?
an electromagnet requires electricity and you will have to pay for it. permanent magnets are always on and you can change the strength of it.
