What happens when you stroke a needle 20 times with a magnet?
it becomes magnetic :)
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.
Explain why a compass points in a north-south direction?
a compass is a free-spinning magnet. When it interacts with the magnetic field lines of the earth, if the compass is not parellel to the field lines, it will spin. Just like a weather vane will move if it isn't parallel to the wind, the magnet will experience a force from the field lines causing the needle to move. When the needle is aligned with the field lines, it has reached an equilibrium since a deflection either to the east or west will experience a force pushing the northern half of the needle to north. So, essentially think of the magnetic field lines as a north-south wind and the magnet as a weather vane.
What was William Gilbert's theory about why compasses worked?
He found that Earth has a magnetic field also known as magnetosphere
Why does a compost attract to a north magnetic and repel by the south?
OK- first, it is a compass. The needle of a compass is a magnet. It points to the Eath's Magnetic Poles- the two spots where the Earth's magnetic field comes out of the ground. In magnetism, opposites attract, likes repel.
Is A compass needle permanent a magnet?
Compass needles are permanent magnets. in response to the Earth's magnetic field, the compass needle will point toward the geographic North Pole.
Is the magnet in a compass a permanent magnet or a electromagnet?
The magnet in a compass is a permanent magnet. Its magnetic field aligns with the Earth's magnetic field, allowing the compass needle to point north.
Is a compass a permanent magnet?
Compass needles are permanent magnets. in response to the Earth's magnetic field, the compass needle will point toward the geographic North Pole.
What is the magnet in a compass?
The compass needle.
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.
Is the magnet in a compass a permanent or electromagnet?
The magnet in a compass is a permanent magnet. It retains its magnetism without the need for an external electrical current.
What is a example of a magnet?
A compass needle.
Is the magnet in a compass a permanent magnet or electronic?
A. Compasses typically use a permanent magnet.
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.

How far do you need to keep a magnet from a compass?
To avoid interference, keep a magnet at least 15 cm (6 inches) away from a compass. This distance prevents the magnet from affecting the compass needle's orientation.
What happens when a compass is brought closer to a magnet?
When a compass is brought closer to a magnet, the compass needle will align itself with the magnetic field of the magnet. This alignment occurs because the magnetic field of the compass interacts with the magnetic field of the magnet, causing the needle to point towards the magnet.
What does a compass does when it detects a magnet?
The needle goes to the magnet because of the pull!!!
