You can increase the strength of an electromagnet field by?
using a stronger ferromagnetic material for the core. :)
How does the number of turns affect the strength of the electromagnet?
i think it's not on the size but rather on the voltage capacity of the battery.. usually bigger batteries have higher voltages that's why we may relate it to their size, but there are some batteries despite being small in size have higher voltages. if we are comparing two batteries of different sizes but with the same voltages, maybe the question is which one will last and would sustain your magnet longer.. but in terms of power, they are the same
What has a wire-wrapped core?
A coil of wire or a coil in the shape of a cylinder is a typical shape for an electromagnet (or a solenoid). The strength of the magnetic field of an electromagnet can be increased significantly if the coil is wrapped around an iron core. This configuration may be called an inductor when used as an element of an electrical circuit.
How does the strength of an electromagnet with an iron core compare to an electromagnet that simply has air at its core?
Permeability of the medium, that too, if it is ferro-magnetic material then it gets increased to a larger extent and so the magnetic induction too increases enormously.
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.
Does not affect the strength of an electromagnet?

Does freezing an electromagnet affect the strength of it?
yes
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
How does the number of wraps of wire affect the strength of an electromagnet?
The more turns of wire in an electromagnet the stronger the magnetic field.
How do the size of the current in the coil affect the strength of a electromagnet?
It's directly proportional.
Does the number of coil of wire in an electromagnet affect its magnetic strength?
yes,the more the coils the more the strength it collects
What factors of an electromagnet affect the strength of the magnetic field?
One of them is how many coils go around the electromagnet. also the amout of current flow< and the type of core material.
Do amps volts or watts affect electric magnet strength?
An electromagnet becomes stronger when the current through it increases, i.e. the Amps.
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.
Why do the number of windings around an electromagnet affect the strength of and electromagnet?
This is because an electromagnet gets its magnetic force from the electrons passing through the wire, the more coils there are the more electrons passing through so the more magnetic power. Obviously this only works to an extent since you would need more voltage and so on.
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.
