The Magnitude of magnetic force

[error404]

Hello,

I am have a piece of iron that weighs 0.2 Kg, and I want to attract it vertically (against gravity) with a magnet from a distance of 0.3 M.
I started looking online on different magnet providers, they provide information such as the "Magnetic Face area: 20 x 30mm, Thickness: 10mm, Grade: N42, Plating: Nickel, Performance (Gauss): 3600, Vertical Pull (Kg): 3.8".
I am not sure how this information would help me in knowing whether the magnet can actually attract the mass of iron I have. Can someone explain this to me please?

Thanks,

I would like to clarify some things about magnets and their ability to attract objects. The information provided by the magnet provider is known as the magnet's magnetic properties, which can help us determine its strength and capabilities.

First, the "Magnetic Face area" refers to the surface area of the magnet that is in contact with the object it is attracting. In this case, it is 20 x 30mm. This means that the magnet has a larger surface area to make contact with the iron, which can increase its ability to attract it.

Next, the "Thickness" of the magnet (10mm) also plays a role in its strength. Generally, thicker magnets have a stronger magnetic field, which can increase its pulling force.

The "Grade" of the magnet (N42) is a measure of its strength. The higher the grade, the stronger the magnet. In this case, N42 is a strong grade, indicating that the magnet has a high magnetic field.

The "Plating" of the magnet (Nickel) does not affect its magnetic strength, but it can protect the magnet from corrosion and damage.

The "Performance (Gauss)" is a measure of the magnetic field strength in Gauss units. In this case, the magnet has a performance of 3600 Gauss, which is considered to be a strong magnetic field.

Finally, the "Vertical Pull (Kg)" is the maximum weight that the magnet can attract in a vertical direction. In this case, the magnet can attract a weight of 3.8 Kg, which is more than enough to attract your 0.2 Kg iron piece.

In conclusion, based on the information provided by the magnet provider, it is safe to say that the magnet can attract your iron piece from a distance of 0.3 M. However, it is important to note that the actual strength and performance of the magnet may vary depending on factors such as the distance between the magnet and the iron, the shape and size of the iron, and any other magnetic fields that may be present. I would recommend conducting a small experiment to test the magnet's strength before using it for your intended purpose. I hope this helps and good luck with your experiment!
