The distance at which magnets can attract each other depends on the strength of the magnets. Generally, the attractive force decreases as the distance between two magnets increases, following an inverse square law. For small magnets, the typical attraction distance is a few inches, but for larger or stronger magnets, it can be several feet.

What is atracted to magnets?
Ferromagnetic materials such as iron, nickel, and cobalt are attracted to magnets due to their alignment of magnetic domains in the presence of a magnetic field. Other materials such as steel and some alloys can also be attracted to magnets to varying degrees.
How far apart can a magnet be to stick to something?
It depends mostly on how strong the magnet is and how much iron, nickel, cobalt is in the substance its supposed to stick to, as these elements are the only common substances that readily stick to magnets, except other magnets or electromagnets. A premium quality, N45 purity neodymium based permanent magnet in the form of a 1 inch x 1 inch x 1 inch cube, for example, can pull a another magnet of the same type several inches away and steel staples as far away as a hand length (the length between the tip of your thumb and the tip of your pinky, with all your fingers spred out). On the other hand, a magnetite refrigerator magnet (about the worst type of magnet there is) would have to be less than half an inch away from steel staples to attract them. Keep in mind that the actual range of a magnetic field is infinite, but because of the physical properties of such fields, their strength is only noticeable when very close to their source. Therefore, the "significant" range of a magnetic field depends on how strong its source is.
Do refrigerator magnets increase the energy consumption of a refrigerator due to induction?
No. A refrigerator magnet does not have a strong enough magnet field to affect your motor. Also the motor is mounted either at the top of bottom of your fridge. Far enough away from the outside of the door.
What metals dont stick on magnet?
There are many metals used to make magnets, one of the most common was an alloy called alnico for it components: aluminum, nickel, and cobalt. However there are much better magnetic alloys now that I don't know the names of.
How far does a magnetic field extend?
The extent of a magnetic field depends on the strength of the magnet producing the field. In general, the magnetic field of a permanent magnet extends a few times the physical size of the magnet. For electromagnets or large magnets, the field can extend several meters.
How far does a magnet have to be to attract certain things?
The distance at which a magnet can attract certain objects depends on several factors, including the strength of the magnet, the material of the object, and the presence of other materials or magnetic fields. Generally, stronger magnets, like neodymium magnets, can exert a noticeable attraction over several centimeters, while weaker magnets may only attract objects from a few millimeters away. However, for most common ferromagnetic materials, the attraction diminishes rapidly with distance.
How do magnets get stronger?
Magnets can get stronger by being exposed to strong external magnetic fields that align the magnetic domains within the material. Additionally, heating a magnet above its Curie temperature and then cooling it in the presence of a magnetic field can help increase its strength. Using materials with higher magnetic properties can also lead to stronger magnets.
Why is a steel attracted to a magnet?
Magnets are just certain minerals that create a strong magnetic field. Everything in the universe, down to our atoms, creates a magnetic field (which is why you can't walk through walls, even though the atoms in you are relatively far apart from one another). Some metals (such as iron) have a magnetic field that is attracted to the field from a magnet. So, the two objects, if given the opportunity, will try to go nearer to each other.
Will a magnetic attract gold?
No, gold is not magnetic. A gold coin that is attracted to a magnet is almost certainly gold plated over an iron or nickel base (though nickel is far less magnetic).
What makes powerful magnet?
Really powerful magnets are alloys or in some cases not even metals (they're minerals like metal oxides). Iron is one of the better "pure" metals.In alloy or oxide magnets, the metals themselves don't even have to be ferromagnetic; an alloy of aluminium, cobalt, and iron was discovered in 1931 to make far better magnets than iron itself did, even though aluminium is not ferromagnetic at all.
Can you have a unipolar magnet?
No. No matter how far you divide a magnet down, there will always be two poles: North and South. Well ; there is actually a domain in magnets which divides it into N and S. If the magnet is smaller than that, ie a few nanometers, then you can have unipolar magnets. In fact , such objects have been synthesized.
What is atracted to magnets?
Ferromagnetic materials such as iron, nickel, and cobalt are attracted to magnets due to their alignment of magnetic domains in the presence of a magnetic field. Other materials such as steel and some alloys can also be attracted to magnets to varying degrees.
Which are some of the stores that one might find to buy magnet motors?
As far as can be ascertained from researching this question, there are no stores where one can buy magnet motors as they are not a proven technology. One can, of course buy magnets at many stores.
Which type of magnet can easily be magnetized and demagnetized?
An electronic magnet is by far the easiest because you magnetize one by hitting a button (or for home made magnets) connecting a wire, and demagnetizing by hitting the button again or disconnecting the wire.
How far apart can a magnet be to stick to something?

Can a magnet affect digital scales?
Well, honey, a magnet can mess with the accuracy of a digital scale because it can interfere with the sensors inside. So, if you want your measurements to be on point, keep those magnets far away from your digital scale. Don't go blaming the scale if you've been playing around with magnets and your weight suddenly fluctuates like a yo-yo.
Can you attract Jupiter with a magnet as big as it?
No, you cannot attract Jupiter with a magnet regardless of its size. Jupiter is a gas giant composed mostly of hydrogen and helium, lacking a significant magnetic or metallic core that could be influenced by a magnet.
