Faraday's Rotating wire experiment - Question (1 Viewer)

[ownagemaster]

Hi

I have recently been given a question in class relating to Faraday's rotating wire experiment. The question asks 'Discuss why this device might be called a motor'. I'm absolutely stuck on this one for some reason. I thought that it might have something to do with the fact that it uses the motor effect to drive its motion. Any help would be appreciated.

Thanks

what is faraday's rotating wire experiment? didnt faraday discover the generation of an electric current by moving a magnet into a wire which is produced into a coil or somethin?

well actually faradays law is like this

as a wire cuts lines of flux it wil experience a change of flux causing a seperation of charge, and thus creating an electric field, and inducing an electric field and a current should the circuit be closed.

What is a motor?

Something that produces KE. This produces KE and can move something so its a motor.

But it is a discuss, so you should also be saying why it isn't a motor.

*EDIT (due to mistake found by helper)*

eerrr technically a dc* motor is a combination of:

a rotor
an armature
a stator (usually the magnets)
a coil
a power supply
a split-ring commutator
some carbon/copper brushes

and involves taking electrical energy and transforming to mechanical energy through the interaction of the magnetic fields of the coil and stator

*NEW*
the ac motor does not require the commutor as the current alternates as the flux becomes + & -

err technically no. It consists of a rotor and a stator. Induction motors and AC motors don't fit your description.

It's more of a generator...

Guys, how did you get to Motors and Generatos that quickly ?
I only have a Space assessment topic tomorrow.

i dont know about the other guys f3nr15 but at my school we do motors/generators before doing space... maybe the other schools are like this too

Really? My school does the topics in order. We do The Acidic Environment before Production of Materials for chem, though, don't know why o.0

So how far down the track does Faraday come in and is the Faraday experiment the equivalent to the Michelson-Morley experiment in terms of significance only ?

I'd like to know why CaCO₃ is alkaline even though it does not contain OH^- ions.

what do u mean 'in terms of significance'?

what do u mean 'in terms of significance'?

I must rephrase.

The Michelson-Morley experiment was very important in science because no aether was found to exist.

What is the importance of Faraday's experiment ?

short version.
faradays experiment showed that should a conductor cut lines of flux it will induce an emf

longer version
should a conductor cut lines of flux it will experience a change of flux, a change of flux results in a seperation of charge. a seperation of charge results in an emf and should the circuit be closed a current will also be induced

for the direction refer to lenz's law
