What do you call a magnet that only lasts a short time?
A temporary magnet is a magnet that only retains its magnetism for a limited period before losing its magnetic properties.
What type of magnet can only attract materials when it is touching another magnet?
A temporary magnet, such as an electromagnet, can only attract materials when in contact with another magnet or when an electric current is flowing through it. It loses its magnetism when the current is turned off or the magnetic field is removed.
Will a magnet attract aluminium foil?
No, aluminum is a non ferrous. Only ferrous metals can be attracted to a magnet.
How did a magnet become a magnet?
A material becomes a magnet when its domains align in the same direction, creating a magnetic field. This alignment can be achieved by exposing the material to a magnetic field or by rubbing it with an existing magnet.
Does a magnet attract dime?
No, a magnet does not attract a dime. Dimes are made primarily of a copper-nickel alloy, which is not magnetic. Only materials that contain ferromagnetic metals, like iron, cobalt, or nickel, will be attracted to a magnet.
If a magnet is held close to a coil of wire will it cause current to flow?
Yes, but only if the magnet or the wire are kept moving.
How many paperclips are in a yard?
It only takes one to damage the lawnmower.
What hapens if a magnet gets wet?
When a magnet gets wet, the liquid acts as an electrical conductor when moving through the magnetic field and produces a voltage. You can test this theory by dropping a magnet in a fish bowl and watching the fish float to the top. Don't worry, it is only a mild electric shock and the fish should start swimming around again within a minute or so.
Of a ferromagnet an electromagnet a temporary magnet or a permanent magnet which is easy to create but loses its magnetism easily?
The temporary magnet becomes a magnet in a strong magnetic field, but its magnetic properties will disappear when that field is taken away. The ferromagnet and the permanent magnet are essentially the same thing. The electromagnet isn't that easy to make compared to the temporary magnet. Let's conduct an esperiment. If we take a bar magnet and pick up a paperclip with it, we can use the paperclip on the end of the magnet to pick up another paperclip. The second paperclip we are picking up only needs to touch the first paperclip; it does not have to touch the magnet itself. When the magnet is taken away, the paperclips no longer exhibit magnetic properties. They were acting as temporary magnets, and the simple and easy removal of the magnet cause them to lose their magnetism.
Why does a paper clip stick to a nail when it's on a magnet?
The nail contains iron, which is ferromagnetic. Ferromagnets respond to a magnetic field (from a magnet) by generating their own magnetic field, ie, they become a magnet in the presence of a magnet. They also exhibit hysteresis, in that if they are exposed to a strong enough magnetic field, it will lock in and become a permanent magnet.
What is identification of magnet?
repelsion is the only identity of magnet
I have an American 1944 Lincoln's head penny that does not stick to a magnet how much is this worth?
About 3 cents in average circulated condition. It's the 1943 that gets expensive if it does not stick to a magnet. Only about a dozen of these copper 1943 cents exist.
What is the theme for Tuesdays with Morrie?
The true meaning of life can be understood only when it gets close to an end.
What do you call a magnet that only lasts a short time?
A temporary magnet is a magnet that only retains its magnetism for a limited period before losing its magnetic properties.
What is true about the magnet if an electric field exists around a magnet?
Then the magnet not only has magnetism, but also an electrical charge.
What is the volume of 5.00 grams?
This question cannot be answered. Remember what grams refers to: mass. Because different objects have different masses, their volumes at a constant mass will be different. For example, 5.00 grams of hydrogen gas will expand to about 4 liters. But if you have 5.00 grams of paperclips, you will only have about 5 paperclips. Both the hydrogen gas and the paperclips have a mass of 5.00 grams, but their volumes are different.
What is 5.03 in a fraction?
166/33 gets close (5.0303030), but to get exactly 5.03, the only solution is 503/100.
