Distance to which magnets start attracting each other

In summary, the conversation is about whether there is a formula to measure the distance at which two equal magnets start attracting to each other. The person is looking at a web page and needs to know this information before ordering more magnets. They also mention that the magnets always interact but the strength gets weaker with distance and their orientation determines whether they attract or repulse each other.

Hi, I was wondering whether it was posible with a formula to measure the distance to which two equal magnets start attracting to each other. I was looking at this web page https://www.kjmagnetics.com/blog.asp?p=surface-fields-101 and I am not sure if this is the right formula.

I have two Neodymium Magnets N52 with a radius of 0.5" and a length of 1.5". I am looking for a formula because I need to order more magnets and I need to know this before I order more. Thanks

Any help or comment is appreciated.

Daniel

They always interact regardless of the distance, although thte strength gets weaker with distance. Whether they attract or repulse each other depends on their orientation.

FAQ: Distance to which magnets start attracting each other

What is the distance at which magnets start attracting each other?

The distance at which magnets start attracting each other depends on several factors, such as the strength of the magnets, the orientation of the magnets, and the presence of any barriers or other objects that could affect the magnetic field. Generally, magnets need to be within a few inches of each other in order to start attracting.

Can magnets attract each other from a long distance?

In general, magnets do not have a strong enough force to attract each other from a long distance. The strength of the magnetic field decreases rapidly as you move away from the magnet, so they need to be relatively close to each other in order to attract.

What is the maximum distance at which magnets can attract each other?

The maximum distance at which magnets can attract each other depends on the strength of the magnets. Stronger magnets will be able to attract each other from a greater distance compared to weaker magnets. However, this distance is still limited and they will eventually reach a point where they are no longer able to attract each other.

How can I increase the distance at which magnets attract each other?

The distance at which magnets can attract each other can be increased by using stronger magnets or by increasing the strength of the magnetic field. This can be achieved by placing the magnets closer together, using larger magnets, or placing them in an environment with less interference from other objects.

Is there a difference in the distance at which magnets attract depending on their shape?

The shape of a magnet does not significantly affect the distance at which it can attract another magnet. However, certain shapes, such as horseshoe or bar magnets, may have a stronger magnetic field compared to other shapes, which could result in a slightly longer attracting distance.
