Heat does not hold a straight pin to a magnet; rather, it can affect the magnet's properties. When heated, certain magnets can lose their magnetism due to a phenomenon called thermal demagnetization. However, if the pin is made of ferromagnetic material, it can be magnetized and attracted to the magnet when at a lower temperature. In summary, heat itself does not hold the pin to the magnet; it's the magnetic properties of the materials involved that determine the attraction.

How does a magnet attract pins?
Stroke a magnet down the length of the pin repeatedly. The proximity and movement of the magnet along the pin cause some of the iron molecules to become aligned like those in the magnet. The more strokes, the stronger the magnetic field in the pin will become, up to a certain threshold (the number of iron molecules available and able to align in the pin is limited).
Will a North Pole repel a drawing pin?
Yes, a North Pole of a magnet will repel a drawing pin if the pin is made of a ferromagnetic material, such as iron, because the magnetic field of the North Pole will induce a south pole in the pin. However, if the drawing pin is not magnetic or made from a non-ferromagnetic material, it will not be affected by the magnet at all. In most cases, drawing pins are not magnetized, so they would not be repelled by the North Pole.
Can a magnet have 3 poles?
Of course . You can make such a magnet easily using a safety pin. Take a safety pin and magnetize it using a permanent magnet. Then unfold it. The ends will have same poles and at the middle you will have the other. So you can have a magnet with three poles. Verify it using compass.
How do you magnetize a dress maker's pin?
You can magnetize a dress making pin by stroking it in one direction with a permanent magnet. I have done it using a good quality fridge magnet. Dress making pins may become magnetized when they are dropped on a hard surface, for example a tiled floor.
Why does a compass have lightweight magnet and frictionless bearing?
The pointer/magnet provides the opposite attractive force to align itself along the earth's magnetic field. The pointer/magnet must be lightweight so that it responds rapidly to turning, and so that it reduces friction from its weight as it rests on the supporting pin. The so-called "frictionless" bearing (the supporting pin) allows the compass pointer to spin freely in order to achieve said alignment with the earth's magnetic field. Low friction is necessary to allow the weak magnetic force on the pointer to overcome the friction between the pointer/magnet and the supporting pin.
Why does rubbing a pin with a magnet make it magnetised?
When you rub a pin with a magnet, the pin's domains align in the same direction as the magnetic field produced by the magnet. This alignment leads to the pin becoming magnetized, with its own north and south poles.
How does a magnet attract pins?
Stroke a magnet down the length of the pin repeatedly. The proximity and movement of the magnet along the pin cause some of the iron molecules to become aligned like those in the magnet.

Why does a pin attracted by a magnet move upwards and not downwards towards the earth's gravitational pull?
The force of attraction between the pin and the magnet is greater than the force of gravity acting on the pin. As a result, the pin moves upwards towards the magnet instead of being pulled downwards by gravity.

How would you identify the pin on an LED?
there is a part of the circle that is straight. the pin closest to that straight part is negative
Will a steel drawing pin attract to a north pole magnet?
Yes, a steel drawing pin will be attracted to a north pole magnet because it is made of a ferromagnetic material (steel) that can be magnetized by the magnetic field of the magnet.
Explain why a magnet can attract pins but not matches?
A magnet is made of 'Soft' Iron. A pin has steel (iron) in it. A match does NOT have iron in it.
Can a safety pin become a temporary magnet?
Yes but not for very long.
What was the significance of the safety pin?
It holds things closed.
What is the pin that holds the record in place called?
The pin that holds the record in place is called the spindle. It helps to center and secure the record while it's playing on a turntable.
What is the pin code for club heat?
The master pin code for DVD Club Heat is not available online. Each PIN is single-use only and has to be paid for.
