What cause deviation in a magnetic compass?
The compass needle will only align itself with the magnetic meridian if it is free from all other influences except the magnetic field of earth.This is rarely so, particularly on a ship which constructed on steel. The magnetism induced in the steel by the earths magnetic field causes the compass needle to deviate from the magnetic meridian, by an amount which is called the DEVIATION.
Why does a compass spin when it is placed next to a magnet?
A compass needle is a small magnet itself. When it is placed next to a larger magnet, the magnetic field of the larger magnet interacts with the magnetic field of the compass needle. This interaction causes the compass needle to align with the magnetic field of the larger magnet, causing it to spin and point in the direction of the magnetic field lines.
What causes the magnetic compass to react with a magnet?
The compass needle is a small bar magnet balanced on a pin. It swivels freely on this balance point. This is how it can align with the magnetic field of the Earth to show what direction magnetic north is. When you introduce another magnetic field, like from a magnet in close proximity, the needle will align with these local fields since their field strength is stronger than Earth's magnetic field - locally.
What causes the magnetic field?
Which magnetic field? If you're talking about the earth, the magnetic poles have switched polarity in the past. The earth is not a solid magnet, it is a liquid, specifically molten nickel. When the molten nickel shifts the magnetic field of the earth can change.
Why needle of tangent galvanometer move by increasing and decreasing current?
The galvanometer is oriented so that the plane of the coil is vertical and aligned along parallel to the horizontal component He of the Earth's magnetic field (i.e. parallel to the local "magnetic meridian"). When an electrical current flow through the galvanometer coil, a second magnetic field H is created. At the center of the coil, where the compass needle is located, the coil's field is perpendicular to the plane of the coil. These two perpendicular magnetic fields add vertically, and the compass needle points along the direction of their resultant He + H. The current in the coil causes the compass needle to rotate by an angle\ \theta.
What causes a compass needle to align with the Earth's North and South poles?
The compass needle aligns to the Earth's magnetic field. This magnetic field is not exactly aligned with the Earth's rotation, but the magnetic south pole is close enough to the geographic north pole for the compass to be useful in most places.

Why can ships with iron hulls causes a compass to become unreliable?
Because the ships might go to different directions(maybe)
How do you show that electric current causes magnetism?
Put a wire carrying an electric current near a compass and it causes the needle to deflect.
What causes a compass to behave as it does?
The needle of a compass is a magnet, and the earth is also a magnet. The side of the compass marked N is attracted to the north pole of the Earth, and the side marked S is attracted to Earth's south pole. The compass will spin to line itself up with the poles it is attracted to. However, if you have other magnets nearby, the compass can spin to line itself up with those instead.

What causes the magnet compass to react with a magnet?
a compass works by detecting the earths magnetic field. a magnet also has amagnetic field just not as big so the compass needle points at the magnet ratherthan towards north.Another AnswerThe compass needle is a small bar magnet balanced on a pin.

How does earths tilt cause the season?
The earth's tilt changes the declination of the sun, thus crating seasons.The sun's declination causes spring summer, fall and winter.
