Usually it's a permanent magnet. You could use an electromagnet instead, but doing so is considerably harder from an engineering standpoint.

What would happen if you put a compass next to a electromagnet?
it farts then it poops
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.

What determines the magnetic polarity of an electromagnet?
Neodymium Iron Boron (NdFeB or NIB) would be the stongest material of an magnet.(Is the tempature which for this material is 12,800 . Hc is the lenth of the material which is 12,300. BHmax is the strenth which is for this material 40 . The other strenth for other materials are 26, 5.5,3.5 . The highest was 40
Is the magnet in a compass a permanent magnet or a electromagnet?
It is a permanent magnet. Electromagnets(as the name suggests) requires an electric source to become a magnet, when the power source is turned off it will not function as a magnet.
What will happen if you put a compass next to an electromagnet that is switched?
the compass's needle will point at the electromagnet
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 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

Why is an electromagnet not use in compass?
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....these among others...
True or False an electromagnet is created when electric current flows through a compass needle?
The real question should be how do you get current to flow through a compass needle.
