They pull a lot of pounds in ratio to their size, I was wondering if it would make any difference in the energy output if you replaced the normal magnet with a neodyniam.

A stronger magnet will of course create a stronger flux, but it will create additional drag due to Lentz law and "cogging". As such - the air gap will have to be increased to keep things "equal", or power increased - else the torque and RPM's will decrease, resulting in lower output.
If building from scratch - I would use neos. Reworking an existing unit will probably not be benificial as it would (should) have been designed to work best with the current flux.

The strength of a neodymium magnet is directly related to its size. Generally, larger magnets have a stronger magnetic field and can exert more force than smaller magnets. However, the strength also depends on the specific grade of the magnet, with higher grades having a stronger magnetic field regardless of size.
Yes, larger neodymium magnets are typically more expensive than smaller ones due to the increased materials and manufacturing costs. However, the price also depends on the grade and type of magnet, with some larger magnets being more affordable than smaller ones.
It depends on the specific project and what you are trying to achieve. If the smaller magnet has a strong enough magnetic field to fulfill the desired function, then it can be used instead of a larger one. However, if a larger magnet is required for the project to work properly, then a smaller one may not be suitable.
Yes, larger neodymium magnets can be very strong and may pose a safety hazard if not handled properly. They can attract to metal objects and may cause injury if they snap together or if a finger gets caught between them. It is important to handle all magnets with care and follow proper safety precautions.
Yes, neodymium magnets can lose their strength over time due to a process called demagnetization. This can occur if the magnet is exposed to high temperatures or strong magnetic fields, or if it is dropped or bumped. However, with proper care and handling, neodymium magnets can retain their strength for a very long time.
