Comparing Strength of Electromagnets and Neodymium Magnets at 4 oz and 12v

AI Thread Summary
When comparing the strength of electromagnets and neodymium magnets at 4 oz and 12v, electromagnets generally scale better for larger applications, while neodymium magnets are preferable for smaller quantities. Electromagnets are not limited by voltage but by current, which can lead to overheating if not monitored, especially with a 2 Amp power supply. For applications exceeding 1 lb, using electromagnets with an iron core is recommended. Neodymium magnets are effective for lighter loads due to their strong magnetic properties. Overall, the choice between the two depends on the specific weight and application requirements.

Which one is stronger given they are the same size and weight? Say 4 oz.

Just say you only have 12v to work with on the electromagnet.

Electromagnets scale better then neodymium.
For small quantities, I would say go for neodymium.
Anything past 1lb or so, I would use electromagnets with a iron core.

Also, electromagnets aren't limited by the voltage, but rather the current (as its essentially a short circuit)
I've used 2Amp power supplies before, however you need to keep an eye out on the electromagnet as it will warm up and burn out quickly.
 
That's good news. Thanks for the info you saved me tons of time.

Thread 'Weird near-field phenomenon I get in my EM simulation'

I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...

Thread 'EMF (Electromagnetic Field) & EHS (Electromagnetic Hyper Sensitivity)'

Hello dear reader, a brief introduction: Some 4 years ago someone started developing health related issues, apparently due to exposure to RF & ELF related frequencies and/or fields (Magnetic). This is currently becoming known as EHS. (Electromagnetic hypersensitivity is a claimed sensitivity to electromagnetic fields, to which adverse symptoms are attributed.) She experiences a deep burning sensation throughout her entire body, leaving her in pain and exhausted after a pulse has occurred...
