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
What happen when you change the direction of current in an electromagnet?
If you change the direction of current in an electromagnet, (which by the way is just a coil of wire) then the direction of the magnetic field will also be reversed: That is to say, what was north is now south. If you want more info. look up "the left hand rule".
What does an electromagnet operator do to release metal attached to the electromagnet?

What is a solenoid with a ferromagnetic core called?
Its called an electromagnet
What happens if the current of an electromagnet is changed?
The field strength of an electromagnet (and the shape of that field) will largely be determined by the physical characteristics and geometry of the coil (wire size, number of turns, spacing of turns, diameter of coil, etc.), the current flow through the coil's wire and the material and shape of the core. The most variable aspect of the electromagnet is the current we run through it. Once the electromagnet is designed and constructed, the limits are "built in" and about all we can vary is current. Use the link to the GSU Hyperphysics site and it's diagram of an electromagnet. (Be sure to scroll down a bit.) Also, look around on that site, if you have time. There is a lot of good basic physics there. The explanations are very reader friendly and the diagrams are pretty good, too.
What are 4 factors to change an electromagnet?
6924
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.

What is 1 variable that I'm going to change in the experiment electromagnet?
You have to change the core
How does the magnitude change with each number on the scale?
10x the strenght per 1 magnitude.
What describes the role of an electromagnet in a generator?
Its role is to change mechanical energy into electrical energy.
What best describes the role of an electromagnet in a generator?
Its role is to change mechanical energy into electrical energy.
Which change will most likely increase the strength of a magnetic field produced by an electromagnet?
Add a battery
