Solenoids are made of magnets that are able to conduct electricity. This is what is commonly referred to an electromagnet which creates a stable magnetic field.

What is temporary magnet made up of a wire wrapped around a core?

A temporary magnet made up of a wire wrapped around a core is called an electromagnet. When an electric current flows through the wire, it creates a magnetic field in the core, turning it into a magnet. This type of magnet can be turned on and off by controlling the flow of electricity.

no,it can not be picked by a magnet because it is not made of iron, steel, nickel ,& copper


What can pick up things that are made of iron?

A magnet can pick up things that are made of iron because iron is a ferromagnetic material, meaning it is attracted to magnets.

What is One use of an electromagnet?

Electromagnets may be used for a wide veriety of things, from scrap cranes, electrical componants such as solenoids and relays, or in science for partacle acceleration and mass spectroscopy. they are good for when you want a magnet that can be turned off to release whatever is magnetized to it i made one for fun to pick up steel shavings off the shop floor it is hard to clean off a conventional magnet that you cannot turn off


What is the internal structure of a magnet?

As we know every particle is made up of tiny particles called atoms,each magnet is made up of tiny particles called Molecular magnets.Each of them acts as a individual magnet with North and South poles.There arrangement decides the polarity of the magnets


What happens if you put a magnet in a drawer full of nails and the magnet doesn't pick any of the nails?

If the magnet does not pick up any of the nails in the drawer, it could be due to a weak magnetic field of the magnet or the nails being made of a material that is not attracted to the magnet, such as stainless steel. Some nails are made from non-magnetic materials, so they wouldn't be attracted to a magnet.


What type of magnet can be controlled by adjusting the flow of electric current such as might be used in a scrap yard to pick up and then drop large pieces of metal?

An electro magnet.


What type of rock can pick up paperclips?

it would have to be a rock containing the mineral Iron. which would then have to be magnetized to create a temporary magnet, or a permanent magnet if prepared properly


Why won't a magnet pick up a penny or a piece of wood?

A magnet won't pick up a penny because pennies are made of non-magnetic materials like copper and zinc, which are not attracted to magnets. Similarly, a magnet won't pick up a piece of wood because wood is also non-magnetic and does not have magnetic properties to be attracted to the magnet.
