rub against needle with strong magnet i guess
1. Hold a needle by the eye and stroke it gently 30 times with your magnet, in the same direction. Do the same with the second needle, making sure that you use the same end of the magnet.
2. Test your needle-magnets on some pins before you use them for other experiments.
What else can I help you with?
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.
How can I magnetize a needle?
To magnetize a needle, you can rub it against a magnet in the same direction multiple times. This will align the magnetic domains in the needle and make it magnetic.
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
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.
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.
How does a compass needle respond when a compass is placed with a magnetic field?
If a magnetic compass needle is placed in a magnetic Field , its needle deflects and points in the north and south directions
How does a compass needle respond when a compass is placed in a magnetic field?
If a magnetic compass needle is placed in a magnetic Field , its needle deflects and points in the north and south directions
What direction does the magnetic needle of a compass point to?
The magnetic needle of a compass points towards the Earth's magnetic North Pole.
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.
What does force on a magnetic compass needle represent?
The force acting on a magnetic compass needle represents the Earth's magnetic field. The needle aligns itself with the magnetic field lines, pointing towards the North and South magnetic poles. This alignment allows the compass needle to indicate the direction of North.
Why is the magnetic needle deflected?
The magnetic needle is deflected due to the presence of a magnetic field that acts on the needle's own magnetic field, causing it to align in the direction of the external field. This deflection is governed by the principles of magnetism and electromagnetism.
