What is a solenoid with a ferromagnetic core called?
Its called 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
What is the effect of increasing the number of coils of wire wrapped around the core of an electromagnet?
This causes the power of the electromagnet to be increased.

Is the core of an electromagnet a piece of steel put in the center of the coil?
no

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.
Donna is attempting to make an electromagnet to pick up old nails in and around her driveway Which of these materials would be best to use for the core in order to make the strongest electromagnet to?
u need 2 provide more information"Which of these materials would be best to use for the core in order to make the strongest electromagnet to?"u need to provide what "these materials" are
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.
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 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
Does making the core of an electromagnet larger make it weaker?
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.
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
Is the core of an electromagnet a piece of steel in the center of the coil?
no
What does a battery contribute to an electromagnet to help it work?
A core
What is the effect of increasing the number of coils of wire wrapped around the core of an electromagnet?
This causes the power of the electromagnet to be increased.
