What else can I help you with?
Is a nail electromagnet?
Yes, a galvanized nail is still made mostly of iron or steel. The galvanization is merely a coating of zinc.
A piece of magnetic material that retains its magnetic properties after it is removed from a magnetic field?
A material that retains its magnetic properties after being removed from a magnetic field is called a permanent magnet. These materials are able to maintain their magnetization due to their atomic or molecular structure that allows them to have a permanent magnetic field. Common examples include materials like iron, cobalt, and nickel.
Can lodestone pick up paperclips?
No, lodestone is a natural magnet that attracts objects containing iron, such as iron ore or steel. Paperclips are typically made of steel, so a lodestone would be able to pick them up.
What does magnet say he want to do when he is an adult?
be a person who work with animals
Does a south pole attract a piece of unmagnitised steel?
Only if that piece of steel is the north pole of a compass. In short the steel has to be magnetized, and it has to be able to move. A bar magnet resting on the ground would not move because there is too much friction and the force of the magnetic pole is relatively weak. Though apparently if you suspend a bar magnet by a piece of string, it will align itself to the poles.
Is a nail electromagnet?
Yes, a galvanized nail is still made mostly of iron or steel. The galvanization is merely a coating of zinc.
What advantages are there in being to turn a electromagnet on and of?
Being able to turn electromagnetic on and off is what separates it from a normal magnet.
What can a electromagnet not move?
An electromagnet is not able to move objects made of non-magnetic materials, such as plastic or wood. Additionally, if the object is too heavy or the magnet is not powerful enough, it may not be able to move the object.
How many aluminium and steel pins will a magnet be able to hold?

Why can't we use a permanent magnet in a scrap yard?
You need to use an electromagnet in a scrap yard so that you can let go of the pieces of scrap that you pick up. A permanent magnet would not allow you to let go.
Why would electromagnet be used in a recycling yard rather than a strong permanent magnet?
Because with an electromagnet, you can turn it off and on - you can pick things up with it then drop them again.
Why permanent magnet is not used to lift heavy load?
But they are! You can find lifting magnets based on permanent magnets all over in machine shops.
Why won't my split-phase AC motor generate - I've got a Dayton motor I want to use as a generator but no matter how fast I spin the motor it won't generate more than a couple of volts - Help?
You must have a permanent magnet in the field or residual magnetism that produce magnetic flux lines across the rotating conductors. Without an energized coil (electromagnet) or permanent magnet near the conductors, the motor will never be able to create electricity.
What makes electromagnet are different from permanent mangets?
electromagnets are made through a conduction of electricity so they can only be used when the electricity is kinetic. while permanent magnets are use able all the time because the metal in it is active.
What metals attract magnet?
No metals can attract a magnet. Only magnets can attract metals. (Believe me there is a difference). However the most common examples of metals which magnets would be able to pick up are Iron and Steel (steel is an alloy of Iron and Carbon)
A piece of magnetic material that retains its magnetic properties after it is removed from a magnetic field?

These materials are able to maintain their magnetization due to their atomic or molecular structure that allows them to have a permanent magnetic field. Common examples include materials like iron, cobalt, and nickel.
Why can some metals act as permanent magnets?
Certain metals, such as iron, cobalt, and nickel, have electrons that align in a specific way within their atomic structure, creating a magnetic field. When these metals are exposed to a strong external magnetic field, the alignment of their electrons can become fixed, resulting in a permanent magnet. This phenomenon is known as ferromagnetism.
