Why does stroking a needle with a magnet make it magnetic?
Stroking a needle with a magnet aligns the magnetic domains in the needle material in the same direction, causing the needle to become magnetized. This alignment of domains creates a magnetic field in the needle, giving it magnetic properties.
Why does a magnetic needle come to rest in north south direction?
A magnetic needle comes to rest in the north-south direction due to the Earth's magnetic field, which generates a magnetic force that aligns the needle. The Earth acts like a giant magnet with a magnetic north and south pole, causing the needle's magnetic ends to orient themselves along these lines. When the needle is free to rotate, it experiences torque from the Earth's magnetic field until it stabilizes in alignment with the magnetic field lines. This alignment minimizes the potential energy of the system, leading to the stable north-south orientation.
What is a magnetic compass?
A magnetic compass has a needle mounted in a way that allows it to turn freely. Tis needle always lines up with Earth's magnetic field and points toward magnetic north. The needle is set over a diagram that shows east,south, and west. By knowing which way is north, a sailor can find the other diections.

What is the movement of a compass needle that is free to rotate in any direction as you fly from the north magnetic pole to the south magnetic pole?
As you fly from the north magnetic pole to the south magnetic pole, the compass needle will initially point downward at the north magnetic pole due to the steep magnetic field lines. As you move toward the equator, the needle will gradually level out to a horizontal position. Continuing further south, the needle will then begin to tilt upward as you approach the south magnetic pole, ultimately pointing more vertically upward. This behavior illustrates the transition from a downward orientation to a horizontal and then upward orientation of the compass needle in relation to the Earth's magnetic field.
What is a magnetized needle that is attracted to the Earth's North magnetic pole?
It is still a needle, but could be referred to as a compass needle.
Which one mineral causes a compass needle to turn away from North?
Iron is the mineral that causes a compass needle to turn away from North because it disrupts the Earth's magnetic field. The iron in the mineral is attracted to the Earth's magnetic field, causing the needle to align with it.
When the free ends of a tester are dipped into a solution the magnetic needle of a compass shows deflection. Can you explain the reason?
The deflection of the magnetic needle in the compass is due to the flow of electric current when the free ends of the tester, such as a galvanometer, are dipped into the solution. The electric current creates a magnetic field around the tester, which interacts with the Earth's magnetic field, causing the needle in the compass to show deflection.
What is the name of a compass needle?
The needle in a compass is typically called a magnetic needle or magnetic pointer.
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.
How does a compass needle respond when a compass needle is placed within a magnetic field?
A compass needle, as well as everything else on Earth, is ALWAYS within a magnetic field. If the compass needle is free to turn, it will align itself with the magnetic field, and point along the north/south axis of the field. If another magnetic field source appears near the compass ... such as a current-carrying electrical conductor, or a toy magnet in somebody's pocket ... whose field strength is comparable to the Earth's, then the compass will deflect, and realign itself along the north/south axis of the SUM of the fields.

Why does a needle on a compass move?
A needle on a compass is a magnet, and it aligns itself with the Earth's magnetic field. This allows the needle to point towards the magnetic North Pole. The movement of the needle is a result of the interaction between the Earth's magnetic field and the magnetic properties of the needle.
Does a compass needle line up perpendicular or parallel to a magnetic field?
A compass needle will align itself with a magnetic field. It will want to lie along the magnetic field lines, or lie parallel to the lines of force of the magnetic field it is interacting with.
