For an electromagnet, increasing either the current or the number of turns of wire will generate a stronger field.
For a permanent magnet, the strength is limited by what it's made of. Some materials make better magnets than others. This is a topic in the fields of ceramic engineering and Metallurgy, and can't be answered in a simple one-paragraph blurb.
The strong magnet is attracted to the door magnet because opposite poles attract each other - the door magnet was likely oriented to attract the strong magnet. The metal thumbtacks are not attracted to the strong magnet because the magnetism of the thumbtacks is weaker compared to the door magnet.
no it wont because copper is not a type of magnet even though it is a metal
To magnetize a magnet, you can rub it against another magnet in the same direction multiple times. Alternatively, you can expose the magnet to a strong magnetic field in the same direction. This will align the magnetic domains within the material and make it magnetic.
No, a network solid does not make a magnet float over it. The interaction between a magnet and a network solid will depend on the properties of the materials and the magnetic field. In general, a strong magnetic field may influence the behavior of a network solid, but it is unlikely to make a magnet float over it without other external forces at play.
coz if you try to attract a weak and a weak side it wont stick. same with the strong and strong side. But if you put a strong side next to a weak side it will attach. When a strong magnet is brought nearby the domains line up more closely with the magnetic field. The result of this reorientation is an overall magnetization of the weaker magnet.
To get a magnet.Magnets are available in nature.You can make a magnet by tying a piece of iron to a strong magnet for some time.You can also get a magnet by making an Electo-magnet or solenoid.
To make a powerful magnet, use a strong magnetic material like neodymium. Shape it into a magnet by applying a magnetic field while it cools down. Finally, the magnet can be magnetized by rubbing it against a magnet or by exposing it to an electrical current.
The electrons of the permanent magnet would align the way the electromagnetic field passed through the magnet.
Some metals are naturally paramagnetic, meaing that you can induce a magnet field on it but only with a very strong magnet. To actually magnetize the metal itself without a magnet, you would have to make an induced magnet by wrapping the metal around a copper wire and sending electricity through it. It all has to do with the arrangement of the electrons within the metal.
A lodestone is a naturally occurring magnet and is considered to be a strong magnet.
A magnet can move a car, if the magnet is strong enough.
To make a magnet by stroking, you can rub a piece of iron or steel with an existing magnet in the same direction multiple times. This process aligns the magnetic domains within the material, creating a magnetic field in the iron or steel.
The strong magnet is attracted to the door magnet because opposite poles attract each other - the door magnet was likely oriented to attract the strong magnet. The metal thumbtacks are not attracted to the strong magnet because the magnetism of the thumbtacks is weaker compared to the door magnet.
Yes, there is, but external magnets would damage the telephones if the magnet is strong enough. So don't go and try to place the telephone onto a neodymium magnet
it creates a very strong magnet A+ users
Yes, you can turn ordinary iron into a magnet by placing it in a strong magnetic field or by stroking it repeatedly with a magnet. This process aligns the magnetic domains in the iron, making it magnetic.
