I have a student that is trying to design an electric motor. I know
there are a million different (& easy) electric motor designs available.
He is trying something a bit unique.
The student has magnets that state they have a 'strength' of 200 pounds.
I believe that this is the force of attraction btn the magnet and a
ferromagnetic substance when the two are in contact. Is there a high
school method (algebra or calc 1 method) that would make it possible to
calculate:
1- the force of attraction btn two magnets (one electromagnet & one
permanent magnet) when they are separated by some distance?
2- the potential energy of a two magnet system in which the two magnets
are separated?
Your help is appreciated. I haven't used much of my e&m since I took
the course. It appears I've forgotten quite a bit. A bit shameful.
Thanks for your input.
