Magnetic field in a solenoid

A solenoid coil carries an electric current symbolized by several little red spheres in motion. A green arrow shows the direction of magnetic field inside the coil. For other physics animations like this one, please visit http://web.ncf.ca/ch865

where is north?

[PelletierPhysics]

@YOTTR Magnetic field (green arrow) goes from north to south.

is that the current in the direction of proton or electron?

[PelletierPhysics]

The animation shows the conventional current in the direction of positive charges; it's not the flow of electrons.

@PelletierPhysics

so its protons?

[PelletierPhysics]

@beechcraft12 Protons don't move but if they did, they would move in the direction of conventional current.

This is the example why we need to head towards more scope of valuable future animation world... cheers !!!

wow. thats goingt to keep me up.

[g3rrar1]

solenoids are awesome. they are actually electromagnets, wich are used in alot of things

[aweklennon]

how to do this??/ what kind of software we used? can some1 tell me..

[PocaForLive]

The B always points to the nord

[Sposchy]

Thank you!!! This animation explained to me what an entire textbook worth of notes couldn't!

@beechcraft12 all the math is based on conventional current which is in the opposite direction of the electron flow. When they developed the math, they believed that current flowed from positive to negative terminal which is conventional current, but in reality, it flows from negative to positive terminal.

@PelletierPhysics isn't it from south to north ?

love u mannnnnn u solved 1 0f my major problem and misconception

[unpflash]

wow...it spins...
