If they ask about an investigation demonstarte a principle behind Induction Motor then either experiment on motor effect or induced emf is ok ,right???

 

[ND]

Not the motor effect, just induced emf.

 

[Dash]

Ya ya... you have to talk about the induced emf...

The induction motor is different to the motor effect, no?

 

[Rahul]

no its is its complement

a conductor with a current flowing in it will move if a changing mag field is introduced. conversely, when a changing magnetic field is introduced to a conductor, a current will be induced.

both use right hand paml rule

Yep that's right, but this dotpoint is specifically referring to induced emf, cos there is already a dotpoint dedicated to a prac with the motor effect.

oh i dont know, i was just reply to

where can i get info on this prac? my teacher never performed it in class so i dont know what's involved.

 

[Constip8edSkunk]

just demonstrate induction?

get a conductor and move it in a field whilst connected to a galvanometer/voltmeter? or get a coil and spin it in a field while connected 2 a galvanometer/voltmeter?

 

[-X-]

We haven't done this either but i got this from jacaranda.

i remember reading somewhere about using an aluminium disk, a magnet and a pencil to perform this investigation. this procedure seems a lot more complicated...are the two basically the same?

 

[Inhuman]

My teacher showed us both, and I think they're the same except that one's qualitative and one's quantitave

 

[ricenoodles]

would you get marked down for using the quantitative method instead of the qualitative method or vice versa?

 

[ND]

Nah it doesn't have to be quantitative, it just says "demonstrate".
