You would not get a true reading any longer. The forces of the electromagnet are greater than the natural magnetism of the Earth.
it farts then it poops
Yes electromagnet would be attracted to a magnet provided direct current flows through the coil ie when the electromagnet is activated. As unlike poles attract each other the magnet is to placed accordingly. Otherwise repulsion would take place.
The compass would point south, except near positive end of the magnet. It will point north. 6th grade power!!
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
crack
the arrow in the compass would point to the magnet

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...

it would spin around and around.
If compass was not invented we would get lost and cant find ourselves. That's way in TV you see people using compass in the desert.
Magnetite is metal, so the compass would be messed up and not useful at all.

It would lose salt into the water.

it would burst
