If an electric current flows through a wire, it will create a magnetic field. ... a ship or an airplane, it can damage or otherwise change the ship's magnetic compass.

What will happen if you place a magnetic compass in an electric curcuit?
The compass will align itself with the magnetic field generated by the current flow through the wires.
What happen to the magnetic field of a wire when change the direction of the current in the wire?
Direction of the magnetic lines too would get changed
What happen if a north pole of a magnet is kept on the north pole of magnetic compass?
magnetic compass will stop working.
Why would a compass needle move when placed near a circuit?
Any time current flows through a conductor an electromagnetic field is formed around the length of that conductor. The direction of current flow determines the polarity of this magnetic field.
What would happen if the direction of the current through a hall probe is reversed?
The idea is that the magnetic field of the device reacts with the external magnetic field. If the current is reversed, the magnetic field would also be reversed, and the reading would be the opposite.
What happen to an electromagnet's field if the direction of the current ic reversed?
In that case, the magnetic field will also be reversed.
What has to happen around a coil of wire to generate an induced current?
pass a magnetic field through the coil of wire.
What will happen when the number of turns of wire and the current flowing them increases?
The strength of the magnetic field inside the coil increases.
Is there ever a time when your compass will not point north?
Your compass will always point to the earth's north magnetic pole. That spot is about 940 miles from the real north Pole. Your compass only points to real north if you happen to be on the extension of the line that joins the two spots. Anywhere else, your compass points to one side or the other of the real north Pole.
What happen to the angle of declination as you get closer to the pole?
when you are close to the magnetic north pole, the declination will be so variable and unpredicatable that a magnetic compass becomes all but useless. You also need to consider the effect of local magnetic anomalies and polar wandering. felicity knows whats up<3
What do you use to find true north?
You need to know the variation (also referred to as declination) for your location. Once you have that, you add East variation (or plus) to your magnetic compass reading, and subtract West variation (or minus) from your magnetic compass reading to get true compass reading. To find North, simply line your magnetic compass up so that the needle is on North and then either add or subtract your variation to get the true North reading. See the links below to find the variation for your position.
What would happen to electronics magnets etc if the earths magnetic poles changed?
Nothing - The polarity of an electromagnet depends on the direction of current flow and you can effect the same change in orientation to the earth's field by moving the electromagnet rather than the earth's field.
