Minimum Force of Attraction Between Magnets for Humans

AI Thread Summary
The minimum force of attraction between two magnets that a human can feel is not defined by a specific formula. Sensitivity to force varies based on the body part in contact with the magnets. Humans are more attuned to changes in pressure rather than constant forces. For example, even a slight change in pressure, like a spider moving on the skin, can be detected easily. Overall, the discussion highlights the subjective nature of force perception rather than providing a quantifiable measure.

Hi,

Is it known what is the minimum force of attraction between two magnets needed for a human being to feel an attraction pull between the magnets? or is there a formula for that?

Thanks!

Depends to which body parts you attach the magnets.

just if you hold the magnet with your hand, for example a magnet attracted to a fridge; what is the force that needs to exist between the magnet and the fridge for you to feel they are attracting each other

There's no formula - you're just asking what the weakest force a human can feel is. We're much more sensitive to changes in pressure than to either constant pressures or forces: If there's a spider resting on the palm of your hand, you'll be able to feel it picking up one leg, even though the change in force is minuscule.

Thread 'Inducing EMF Through a Coil: Understanding Flux'

Thank you for reading my post. I can understand why a change in magnetic flux through a conducting surface would induce an emf, but how does this work when inducing an emf through a coil? How does the flux through the empty space between the wires have an effect on the electrons in the wire itself? In the image below is a coil with a magnetic field going through the space between the wires but not necessarily through the wires themselves. Thank you.

Thread 'Reflections at the source point of a transmission line'

I was using the Smith chart to determine the input impedance of a transmission line that has a reflection from the load. One can do this if one knows the characteristic impedance Zo, the degree of mismatch of the load ZL and the length of the transmission line in wavelengths. However, my question is: Consider the input impedance of a wave which appears back at the source after reflection from the load and has traveled for some fraction of a wavelength. The impedance of this wave as it...
