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.

You can increase the strength of an electromagnet field by?
using a stronger ferromagnetic material for the core. :)
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.
Why is iron nail used to make an electromagnet?
because exhibits maximum flux density requires small magnetising field exhibits low hysteresis loop
What object is not needed for making a electromagnet?
Every thing except a conducting wire, battery and a soft iron core is not needed for making an electromagnet
Does electricity flow through iron?
Electromagnets are magnets that are powered by electric currents. An electromagnet is usually more powerful than a permanent magnet that does not use electricity because the strength of an electromagnet can be increased by adding additional material, such as more wire or a bigger core, and the magnetic field can be concentrated using wire coils around the core. i hope this did help
How does the strength of a wooden core electromagnet compare with that of the iron core electromagnet?
Electromagnets consist of wire coiled around a core. The core can be anything from air to a nail or even a pencil. Since electrons flow freely through a conductive core (like a nail), an electromagnet made with a metal core will have a larger magnetic field (and thus be stronger) than an electromagnet with a wooden core. The strength of an electromagnet is related to the number of times the wire is coiled around the core and the distance the wire covers across the core. The more coils wrapped closer together, the stronger an electromagnet will be. The amount of voltage running through the wire also plays a role in an electromagnet's strength. More voltage means more electrons moving through the wire and thus a stronger magnet.

An electromagnet would have the greatest strength if its wire were wrapped around a core made of what?
iron
What makes a electromagnet stronger than a solenoid?
The strength of an electromagnet is determined by the number of windings, the current flowing through the windings, and the permeability of the core.
What does the strength of an electromagnet depend on?
It depends on electrical current,the number of winding,and core materials <3
On what factors does the strength of an electroment depends?
The strength of electromagnet depends on the electric current flowing through the core because when the current is stopped, the core is no longer magnetized and the rate of change of flux linkage.
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.

Can you use an aluminum core for the magnet?
I cannot remember for sure, but in an electromagnet, an aluminum core would not have any permeability to add to the electromagnet's strength. An electromagnet is more efficient when a thicker core is used; it generates more power. The material you use should be prone to magnetism, as in attracted by permanent magnetic apparatuses or the such. So, an aluminum bar/core (cannot be magnetized), like you stated, wouldn't be the best choice for your magnet's core.
Does the size of the core affect the strength of a electromagnet?
That's because the strenght of the electromagnet is related to the number of coils then, the more coils gets more strenght because as you add more coils to the electromagnet you have more and more magnetic field. -I hope this answer helps you if you have a question regarding any questions on any subject please fell free to ask. Thank You
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 is the description of electromagnets?
An electromagnet is simply a coil of wire. It is usually wound around an iron core. However, it could be wound around an air core
