motor installation question
hi there...
i am about to mount my (my1018)motor to my bicycle i have noticed the metal i am using to mount the motor,sticks to the motor because of a magnet that is in the motor... is this a bad thing,will it reck or ruin the motor**********? thanks for your time hope to hear from you soon take care alex |
Motors are made up of MAGNETS and copper wires. Your forks are made of steel, so the magnets will be attracted to them. All is normal. Carry on. :thumb:

FYI, homebrew outrunner motor builders use a "paper clip test" to make sure the iron bell (which holds the magnets) is thick enough - if a paper clip is attracted to the bell, it is too think and losing some efficiency. |
this may sound silly,
but what is a basic definition of ferromagnetic.. does ferromagnetic materials stick or not..my apologies for this question... once again thanks for your information + time.. i really appreciate it.. alex |
Ferromagnetic as in ferrous, which means it contains iron, which means it sticks.
Ferromagnetic materials stick to magnets. |
thanks for that..

Ferromagnetic materials interact strongly with magnetic fields, spontaneously aligning their magnetic dipoles (electron spins). Iron (thus the "ferro") and Cobalt are example of ferromagnetic metals. The magnetic alignment of electrons within a ferromagnetic material carries magnetic fields efficiently through the material, enabling the construction of magnetic circuits.
Ferromagnetism is what we usually mean when we speak of magnetic materials - either as a strong attraction or permanent magnetization. Other materials may be paramagnetic or diamagnetic in the presence of a magnetic field, exhibiting a temporary and typically very weak attraction or repulsion to the field. I don't know if that helps, but magnetism is a very interesting subject. |
definatly helps.
thanks unime |
excercise
heres an idea get of your fat rump and go ride a realbike
|
I definitely won't be doing that anytime soon. Do you know how many Big Macs I had to eat to grow my cankles? I don't think so!
