not always as the south pole of a magnet is magnetic yet it repels another south pole. :D

Are magnets attracted to steel?
The three elements effected by magnetism are Iron, Nickel, and Cobalt. Steel is a iron alloy.Generally speaking, yes , steel is magnetic. But it should be noted that there are a number of steels that are not magnetic. In order to answer this question, you must first identify the type of steel. Steel can also be magnetized[or made to be magnetic] using an electric field.
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.
How long do cheap magnets last compared to more expensive ones?
A permanent magnet will retain its magnetism unless it is affected by a strong outside magnetic or electrical force, or elevated temperatures. If they are not exposed to any of these conditions, permanent magnets will lose magnetism on their own, however this degradation is very slow, on the order of one percentage point every ten years or so.
How would you describe magnetic domains?
Each magnetic domain has a magnetic field. When an external magnetic field is applied, the magnetic domains will partially align, so the magnetic fields reinforce one another - instead of canceling one another, which is what happens when they are randomly distributed.
What does a planet need in order to have Auroras?
A planet needs to have a magnetic field in order to have auroras.
What must a charged particle be doing in order to experience a magnetic force?
A charged particle must be moving in a magnetic field in order to experience a magnetic force. If the particle is stationary, it will not experience a magnetic force.
What must a charge particle be doing in order to experience a magnetic force?
It must be moving
Do magnetics have to touch each other in order to experience a magnetic force?
it only depends on your magnet.
Why is magnetic force a non contact force?
Because it's not necessary for objects to be in contact (touching) in order to feel the magnetic force between them.
Do you need 2 magnets to have a magnetic interaction?
In order to have a magnetic interaction u need 2 objects... do the experiment..1. Get 2 magnets/ buy 2 magnets2. Put them close together and they will have a strong interaction...THATS THE PROOF...
What is principle of maglev train?
Magnetic levitation is the method used for maglev trains. In order to levitate a train, superconducting magnetic coils are used to completely expel the magnetic fields which will cause the trains to fly off its track.

Why do magnetic compasses not point exactly?
Various factors can lead to inaccuracies in magnetic compass readings, such as magnetic variation (difference between magnetic and true north), deviation (magnetic interference from the vessel's metal components), and nearby magnetic fields. Additionally, external magnetic influences like the Earth's magnetic field changes over time can affect compass accuracy.
What precautions need to be taken when using magnetic field therapy?
The primary precaution involved with magnetic therapy is to recognize the expense of this therapy. Magnets have become big business; they can be found in mail-order catalogs and stores ranging from upscale department stores to.
Breaking a magnet will destroy the magnets magnetic properties. True or false?
False. Breaking a magnet into smaller pieces does not destroy its magnetic properties. The resulting pieces will each have their own magnetic fields.
Does a washing machine need a magnet to operate?
No, a washing machine does not need a magnet to operate. Washing machines require electricity to power the motor, control panel, and other components that are essential for washing clothes effectively. Magnets are not a standard component of a washing machine's operation.
