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).
What side is a magnet stronger?
The two sides of a magnet are called the north and south poles. Typically, the magnet is stronger at its poles rather than its sides. The strength of a magnet is usually concentrated at the poles, where the magnetic field lines are closer together and more forceful.
How do you connect a battery to a small motor?
Connecting is simple. The main issue is what kind of motor do you have? Batteries are DC. Therefore the motor must be DC or a universal motor, or a permanent magnet DC motor. The motor voltage and current requirements must match the battery's voltage and ampere-hour rating. A standard DC motor has 4 leads A universal motor has 2 leads A permanent magnet DC motor has 2 leads. The motors with 2 leads are easy: + and -- The 4 lead motor: 2 leads are "field" (F1 F2) 2 leads are armature (A1 A2) one of each goes to + (F1 A1) one of each goes to -- (F2 A2) The motor must be very small in horsepower to work off a battery. There are other more complex DC motors with more leads than 4, but there are NOT going to run on a battery.
Can you determine an unknown substance that contains magnetite by using only one magnet?
Yes, you can determine if an unknown substance contains magnetite by using a magnet. If the substance is attracted to the magnet, it suggests the presence of magnetite or other magnetic materials. However, this test alone will not quantify the amount of magnetite or differentiate it from other magnetic substances. Additional tests would be needed for a more definitive identification.
Why are hydrogen ions attratected to water molecules?
Hydrogen ions are attracted to water molecules because water is a polar molecule with a partial positive charge on the hydrogen atoms and a partial negative charge on the oxygen atom. The positive hydrogen ions are attracted to the negative oxygen atoms in water through electrostatic forces, forming hydrogen bonds that stabilize the system.
An iron nail is more strongly attracted to the?
An iron nail is more strongly attracted to a magnet because the iron nail itself is made of ferromagnetic material, which can become magnetized in the presence of a magnetic field. This causes the iron nail to be attracted to the magnet.
Why does a compass needle spin toward the magnet when yu put it near a magnet?
The compass is a magnet too; and magnets attract each other. More specifically, the north pole of one magnet is attracted by the south pole of another magnet.The compass is a magnet too; and magnets attract each other.

What objects are atracted to a magnet?
Objects that are attracted to a magnet are typically made of materials containing iron, nickel, or cobalt. This includes materials like iron, steel, nickel, and certain alloys. Other materials, such as plastic or wood, are not attracted to a magnet.
What happens when you inadvertanly crossed the positive battery terminal from a negative to a positive and a positive to a negative.?

What positive thinking really means?
It Means more Negitive people will be attracted to you.
How do you use a magnet to tell if something is real gold?
To test if something is real gold using a magnet, place the magnet near the item. If the item is attracted to the magnet, it is not real gold as gold is not magnetic. However, if the item is not attracted to the magnet, it may be real gold. It's important to note that this is not a definitive test and other methods, such as acid testing, are more accurate for determining gold authenticity.
Is red or black positive on a lawn mower battery?
More often than not, the red cable hooks up to the positive post on the battery. There should be a mark on or by each battery post to indicate whether it is the positive (+) or the negative (-) post.
How do you supercharge a magnet?
You can supercharge a magnet by coiling a metal wire around a magnet then hooking both ends of the wire to a battery. Make sure the wire can conduct electricity and the more coils around the magnet, the better.
Why some metals are attracted by magnet while some metals are not attracted by magnets what differences them?
Magnetism occurs only in materials where the electrical charge is unevenly distributed, so that there is more positive charge in one part and more negative charge in another part. I n most materials, the electrical charge is distributed uniformly, in a perfectly spherical manner; however, when this is not possible, the material is said to have a magnetic "dipole" and, if these dipoles line up in the same direction, then the resulting magnetic field can affect the dipoles in other materials and it is called a "magnet".
What is a not affected by a magnet?
Aluminum, copper, and plastic are materials that are not affected by a magnet, meaning they are not attracted or repelled by a magnetic field. This is because they are not ferromagnetic materials like iron or steel, which are strongly affected by magnets.
Is mercury attracted to a magnet?
Mercury, although it does posses some interesting physical and chemical properties, should not be attracted to a magnet. It is considered to be diamagnetic, which means it would actually oppose a magnetic field and repel. If you have more questions on mercury or diamagnetism.
What is the reason that a cold magnet is stronger than a hot or room temperature magnet?
A cold magnet attracts more than a hot magnet. This helps the flow of electricity which therefore helps the electric field, which therefore helps the magnetic field. They use cold magnets to power the LHC which collides hydrogen atoms. Obviously the cold magnet is very attracting.
