Magnetic Field & Neodynium Cube: Strength Comparisons

Click For Summary
SUMMARY

The discussion focuses on the relationship between the strength of magnetic fields produced by neodymium magnets and their configurations. It establishes that the magnetic field does not increase linearly with the number of magnets, as demonstrated through various experimental methods. Participants suggest using superposition to calculate the combined magnetic fields and propose practical experiments, such as measuring the force required to detach magnets from iron and using a spring scale for tension measurements. Additionally, the concept of electromagnetic induction is introduced, highlighting the potential to measure induced voltage by dropping magnets through a wire loop.

Does the magnetic field increase linearly with the number of magnets? For example, will 8 1/2 inch neodynium cubes have the same strength as a 1 inch cube?
Thanks in advance

Do all the magnets have the same magnetization. Well maybe you could use superposition and add all the little B fields together based on distance from a point.
And maybe you could also get an idea of the B field of the little magnet by placing one on a balance and seeing how much weight you had to place on the other end to pull the magnet off a piece of iron or something . Or put the magnet on a spring scale and see how much tension it tool to pull the magnet off a piece of iron and then compare this to the B field of the bigger magnet . The force should be proportional to the fields.
And you might be able to drop your magnets through a wire loop and then measure the voltage
they produce. as the emf is the change in magnetic flux .
