Current direction

[onlyfknhuman]

Which way does current flow in a circuit. i know its positive to negative. but which is the positive terminal. is the LONGER ONE to the SMALLER ONE.

And when a current flows in a solenoid, is current also the direction the NORTH side is at.

its the longer one

i dno what u mean for second part

Dabalyuteeef?

when a curernt flows in a wire, it induces a magnetic field correct?

well if it induces a field that means it has a NORTH and a SOUTH side

u know how magnets they have  a north and a south, and the field goes from north to south

wat r u asking

oh man... when something has a magnetic field. it has a north and south side.

Therefore theres a north and south side in a solenoid, when a current is running. [thats why they can be electromagnets]
However i want to know WHICH SIDE is the NORTH AND SOUTH to find out the DIRECTION of the magnetic field being induced.

You'll have to use the right hand rule. There's no such thing as "the current enters from the north side" or "the current enters from the south side" because the solenoid can be oriented in two different ways.

no one understands me

of course dude!! i know that

if you read my post i asked, which way does current flow inside a solenoid. is it from the POSITIVE OR NEGATIVE TERMINAL.

How to determine the direction of the field it induces? obviously from the direction of current. =_=

i worked this out, scrap this
