What happens if the nail is removed from the electromagnet?

But when you coil the wire around an iron nail, the magnetic domains inside the nail line up and make a strong, temporary magnet. If you disconnect the wire, the magnetic field disappears and the nail is no longer a magnet.

Would the electromagnets have worked if you had used a piece of wood or plastic instead of a nail Why or why not?

Would the electromagnets have worked if you had used a piece of wood or plastic instead of a nail? Why or why not? The electromagnets would not have worked. A piece of metal—such as iron, cobalt, or nickel—must be connected to the circuit to allow electric current to create a magnetic field around the core material.

Can wood be magnetized?

Wood can be magnetized. Nor is the magnet in her hand just any old magnet; it is made of wood and Merk magnetized it herself. “It’s a piece of cake,” says the researcher. To magnetize a piece of wood, Merk soaks it in a highly acidic solution containing iron chloride salts.

Can a magnet pick up a nail?

Anywhere there’s been construction, you’re going to find loose nails, bolts, screws, and similar metal fragments. Only a magnet will pick up metal with such consistency that you can depend on it to clean up parts you didn’t even notice.

Can you turn a paperclip into a magnet?

Paperclips are not naturally magnetic, so, on their own, they will not stick together to form a chain. However, by using a magnet the paperclips can become temporarily magnetized.

Why naked wire is not used in electromagnet?

Originally Answered: Naked wire should not be used to make electromagnet, why? It will short between the windings; the current rather than passing around and around and around the core will just pass across the surface and create no magnetic field (which is proportional to the number of turns it takes around the core).

How many paper clips can an electromagnet pick up?

Increasing the number of turns in the coil of wire did increase the strength of the electromagnet. For example at 20 turns, it could pick up 1 paper clip but at 80 turns it could pick up 3 paper clips.

What happens when you change your magnet with an electromagnet?

What will change is your magnet’s polarity. One end of your magnet will be its north pole and the other end will be its south pole. Reversing the way the battery is connected will reverse the poles of your electromagnet.

Why do nails become magnetic?

The nail will stick to the bar magnet because it will become magnetized. The presence of the nearby north pole rearranges the magnetic domains inside the steel so that their south poles all point toward the north pole of the permanent magnet. As a result, the other end of the nail becomes a north pole.

Is a penny magnetic?

No. Copper or copper and zinc (pennies since 1972) are not magnetic metal. However, steel pennies made during World War II could be magnetized and are attracted to magnets.
