What are not likely to be affected by a magnet?
Organic materials such as plants and animals are almost unaffected by a magnet. In fact, one of the most powerful magnets you are ever likely to see is the electromagnet of a Magnetic Resonance Imaging (MRI) machine.
What metal is used in low melting alloys and magnets?
Several different metals can be used in magnets. Iron is perhaps the most common metal used in permanent magnets, but alloys such as Alnico (Aluminum, Nickel, and Cobalt) can also make very strong permanent magnets.
Is a magnet a insulator or conductor of electricity?
Assuming you mean electrical conductor / insulator, most bar magnets are made of solid metal, either iron, neodymium or an alloy of aluminium nickel and cobalt, so they conduct electricity. There is one type of magnet called a ferrite magnet which does not conduct electricity - they are the type often found in loudspeakers.
What is the most strong natural magnet?
I toyed with neodymium magnets in engineering class at UMD. They were referred by my prof. as the strongest magnetic material yet discovered.
Can an electric motor work without a magnet?
Most electric motors require magnet to operate on the principal of attraction. A motor can operate without any permanents magnets by replacing the with another coil of wire.

Can a magnet stick to a wrench?
Magnets will stick to most wrenches.
Can a magnet and metal propel?
Magnets are most commonly made out of metal, so yes, two metal magnets can repel. But metals such as iron are attracted to magnets even if the metal itself is not magnetized. Iron is attracted to both poles of a magnet, and it can not be repelled by a magnet.
Why magnets slip down the fridge door and onto the floor?
the magnet used on most fridge magnets are low quality magnets, if you find a silver collored magnet you will find it sticks better, try sanding the black magnet off a bit, it might help

What type of magnet is a Refrigerator magnet?
The term "refrigerator magnet" is ambiguous and may refer to any number of types of magnets. However, typically a refrigerator magnet is going to be relatively weak and made of the most inexpensive materials available. Hard refrigerator magnets are likely iron. Flexible refrigerator magnets are made of bonded ferrite powders; barium ferrite is among the most common. In general classification, a refrigerator magnet is a permanent magnet.
How many kinds of magnets are they?
only one... but there are difrent shapes...
The ends of a magnet have the most?
they have the most powerful magnetic fields
Is a bar magnet a permanent magnet?
A permanent magnet is a magnet which will keep its magnetism for a very long time and is difficult to change. No, As I think a permanent magnet means they have abilities to hold the magnetism when they are magnetized. Such as Alnico permanent magnets, but in fact, they can be demagnetized,such as high temperature, hit each other,pulse waves, out magnetic field influence...What's more, different permanent magnetic material, have different abilities on holding magnetism,they can be used in different environments. you can find some details from some manufacturers website, to learn some knowledges.
Are there magnets in our environment?
Ask yourself this: have you ever held a magnet? Then there has been a magnet in your environment. If you mean to ask if there are naturally ocurring magnets, the answer is also yes. Neodymium and Samarium-Cobalt are the two most common.
does magnet sink or float?
Although it does not appear to be magnetic, water, like all matter, may display magnetic characteristics when exposed to a large enough magnetic field. A extremely powerful magnet repels water by a little amount. You may do this yourself if you have a neodymium magnet.
What natural substance attracts metal?
a magnet Actually named magnetite, but it is a natural magnet.
