How could you magnetise a needle to make your own compass?
Rub the needle across a magnetic surface...always in the same direction, don't go back and forth. This will magnetise the needle. Then float the needle in a dish of water. And presto you have your own compass
Compass magnets can only be deflected by electromagnets such as Earth's magnetic field?
Compass magnets align themselves with Earth's magnetic field due to their own magnetic properties. Electromagnets, like the one found in devices such as phones or microwaves, can create magnetic fields that may interfere with a compass's accuracy if they are strong enough and placed close to the compass.
Why does a compass needle change direction when it is near a magnetic field?
Because of the magnetic force. The compass needle is also magnetic.Because of the magnetic force. The compass needle is also magnetic.Because of the magnetic force. The compass needle is also magnetic.Because of the magnetic force. The compass needle is also magnetic.
Will a compass always work?
No. I assume you mean a magnetic compass. A magnetic compass reacts to magnetic fields; the magnetic south pole of Earth is not exactly at the geographic north pole, so at some points of the Earth's surface, the magnetic compass will actually point south instead of north. Also, a magnetic compass will be influenced by other magnetic fields, e.g., current-carrying wires.No. I assume you mean a magnetic compass.

Different types of magnetic compass?
There are three main types of magnetic compasses: the traditional liquid-filled compass that uses a magnetic needle, a digital compass that uses sensors to detect magnetic fields, and a gyrocompass that uses the Earth's rotation to determine direction. Each type has its own advantages and limitations, depending on the specific use case.

Plants with a magnetic force?
Compass plants respond to Earth's magnetic field, but do not produce their own magnetic force.
What metal makes compass go haywire?
Iron can make a compass go haywire as it can create magnetic interference. When a compass is near iron or magnetic objects, it can disrupt the Earth's magnetic field that the compass relies on for accurate readings.
Is gyrosyn compass a combination of magnetic compass and artificial horizon?
No,a Gyrosyn compass is a combination of a Magnetic compass and Direct reading compass.

List the cause and effect connections between the Chinese invation of the Magnetic compass and Zheng He's voyage?
The cause is the Chinese invention of the magnetic compass. The effect is the voyage of Zheng He. The invention of the magnetic compass allowed Zheng He to make his voyage.
What magnetic fild do you detect when you go hiking?
You don't but your compass does: it's the Earth's own magnetic field's polarity and direction.

What characteristic of iron would make it a bad material for housing a compass?
It is magnetic and would throw off your little dial
Why is it a bad idea to make the compass housing out of iron?
Iron is magnetic

Why does a compass point North?
A compass points north because of the Earth's magnetic field. The magnetic field exerts a force on the needle of a compass, aligning it with the magnetic north pole, which is close to the geographic North Pole.
