How can you tell if a nail is rusted by a magnet?

Iron is ferromagnetic and rust is not, but a rusty nail will be attracted by the magnet anyway unless there is no iron left at all, only rust or ferric oxide. If it the case, the magnet will not be helpful, the rusty nail will be so brittle that you will not be able to hold it.

What is the difference in magnetic strength between the two nails?

Answer: Both nail will have approximately equal strength but steel nail will become a permanent magnet and soft iron nail will become normal after the switch is turned off.

Does a nail stick to a magnet?

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.

How does the number of times you slide the magnet on the nail affect the nails magnetic ability?

The temporary magnetism is weaker when moved farther out of the magnetic field of the permanent magnet. When the iron nail is placed in a magnetic field, the nail becomes magne- tized. The closer the nail is to the magnet, the stronger the magnetic field of the nail, and the more paperclips it can pick up.

Where is the magnetic force the strongest on a magnet?

poles
It is strongest at the poles. So, what are magnetic poles? Magnetic poles are opposite ends of a magnet where the magnetic field is strongest.

When magnets are magnetic force is stronger?

The magnetic field of a bar magnet is strongest at either pole of the magnet. It is equally strong at the north pole when compared with the south pole. The force is weaker in the middle of the magnet and halfway between the pole and the center.

What are nails made of?

Nails themselves are made of keratin (say: KAIR-uh-tin). This is the same substance your body uses to create hair and the top layer of your skin. You had fingernails and toenails before you were even born.

How can you magnetize a magnet?

You remagnetize a magnet by bringing it into contact with a strong magnet. So, if you have a weakened magnet, you must carefully bring it to contact with a strong neodymium magnet. This will make your weakened magnet regain its magnetic force. That was it.

What happens when we take two rod in contact with Magnet?

1)When we take two rod in contact with another iron or metal,the magnet attract iron particle but iron rod doesn’t attract. 2)We will hang two rod from middle to a vertical plane and rotate 2-3 times the magnet always stop in same direction every time of rotation but iron rod stop at different direction.

Are two magnets twice as strong as one magnet?

This will help you determine if two magnets are twice as strong. While two magnets together are stronger than one magnet, two magnets will not be twice as strong as one. Why? Two magnets together will be slightly less than twice as strong as one magnet.

What happens when magnets are stuck together?

When magnets are stuck entirely together (the south pole of one magnet is connected to the north pole of the other magnet) you can add the magnetic fields together. Because of this, the magnet on top will be one magnet-height’s distance farther away from the paper clip.

How many Poles does a magnet have?

Each magnet has two poles, the north pole and the south pole. The North Pole gets its name because it is the magnetic north pole of Earth, which is currently near Ellesmere Island in Northern Canada.
