No, the electromagnet is not made weaker by making the core larger. It can be made weaker by decreasing its current and/or turns of coil.

Can an electromagnet have an aluminum core?
The magnetic field will be not be as strong. It will be weaker.
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
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.
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.
What is a solenoid with a ferromagnetic core called?
Its called an electromagnet
What suitable material would you use for the core of an electromagnet?
Iron - use a bunch of iron nails, wrapped many times with insulated copper wire, if making your own electromagnet.
What do the parts of an electromagnet do?
An electromagnet requires only two parts, a core of ferro-magnetic material and wires winding around it. The wires magnetize the core when current flows through them, and the core then creates the magnetic field which the electromagnet is intended to produce.
Can an electromagnet create a magnetic field when the battery is removed?
If the electromagnet has a core, which has become magnetized, then the core will have a residual magnetic field when the power is removed.
What are the 4 ways to make an electromagnet stronger?
Use: More turns of wire A higher current A larger core area A core material with high permeability (soft iron instead of air for example)
What is the central part of an electromagnet?
A ferrous core.
Is earth an electromagnet?
a part of the earths structure causes it to act like an electromagnet
Which has a stronger magnetic field a solenoid or a electromagnet?
A solenoid is an electromagnet An electromagnet is a solenoid with an iron core
