An electromagnet could be used for the pointer of a compass, but there are many reasons why a simple permanent magnet works far better for this particular job.
An electromagnet:
- Requires a power source.
- Has far more mass that would have to balance on the center pin.
- A reliable contact mechanism would have to be invented to connect the needle to the power source.

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
How do i use the earth's magnetic field to tell me where to go?
..get a compass?
When is magnetism lost in an electromagnet?
Magnetism is lost in an electromagnet when the electricity is turned off.
How can a compass be used to check the strength of an electromagnet?
see if a magnet will stick to it someone who knows stuff about magnets please improve this answer. I myself do not know because a magnet will not stick to a very weak magnet but it is still magnetic. EDIT why would you answer if you don't know the answer? You stroke a bar magnet on the material and after a while it either becomes magnetic or not. unless its already magnetic which you would know straight away because it would stick to the bar magnet. sorry if any of my answer doesnt make much sense ... hope i helped someone
Why is magnetic Declination is important?
Because if you need to use your compass to figure out which direction is north,then you need to know by how much the direction the compass points is wrong,and which way. That's the magnetic declination.
What will happen if you put a compass next to an electromagnet that is switched?
the compass's needle will point at the electromagnet
Is a compass an electromagnet?
Usually it's a permanent magnet. You could use an electromagnet instead, but doing so is considerably harder from an engineering standpoint.
What will happen if you put a compass next to a electromagnet that is turnd on?
the arrow in the compass would point to the magnet
How can you test which ends of an electromagnet is the South or North Pole?
Get a compass
Is the magnet in a compass a permanent magnetic or an electromagnet?
PermanentThere is no source of current in a compass, therefore the magnet is a permanent magnet.
What would happen if you put a compass next to a electromagnet?
it farts then it poops
What happens when a compass is placed next to a electromagnet?
the arrow goes to the magnet
Is a electromagnet created when electric flows through a compass needle?
Yes
Is an electromagnet created when electric current flows through a compass needle?
Yes
Is an electromagnet is created whene electric current flows through a compass needle?
no
What would happen if you placed a compass near an electromagnet?
You would not get a true reading any longer. The forces of the electromagnet are greater than the natural magnetism of the Earth.
Is a north or south magnet in a compass a permagnet or an electromagnet?
That's a permanent magnet. After all, the compass doesn't need an electrical current, right?That's a permanent magnet.
