Physics information no1 seems to know

[Mobile1551]

Hey guys, I was looking for this information all over the internet and couldn't find ANYTHING.

My question is: What are the inner workings of a blender?

Either a traditional blender or a magnetic blender, I'm wondering about the physics behind it and I'm thinking about picking this topic for an AP Physics Project but I need to find some websites that have good information.

I was thinking about talking about the magnetic blender more because it seems more complex obviously and I could talk about magnetism being a part of physics. But I'm very confused on how this works. My friend told me that the AC(alternating current) runs through a magnet so the magnetic field is constantly reversing. And somehow this causes the blades to spin...lol

If anyone is intelligent or interested enough in helping me, feel free to write anything. All help would be appreciated ASAP :).

You need some basic understanding of electromagnetism, which you can get after 2 hours of fascinated clicking here: http://hyperphysics.phy-astr.gsu.edu/Hbase/magnetic/motdc.html

Well, Wikipedia is pretty nice too

I'd explain myself but, truth be told, I forgot... I only vague remember something about an accelerated electric field producing a magnetic field of some sort... and so yeah. lol.

Welcome to PF, Mobile.
A basic blender is utterly simple. You have a speed-controlled motor and gear train that drive a set of blades through a coupling joint that consists of interlocking lugs on the top of the base mating with counterparts on the bottom of the canister. The blades themselves are mounted to the lugs through a sealed bearing.
Magnetic coupling just replaces the lugs with powerful magnets set up so that the one in the base 'drags' the one in the canister around due to repulsion/attraction. That eliminates the need for any opening in the base of the canister, and thus any sealed bearings. That's great in one way. On the downside, however, it also severely limits how much torque can be transmitted from the motor.
