Electrical Hexapoles and Multiple Dipoles

02/10/2009 8:18 AM

can there be a electric hexapole?

is it possible to make it with 3 dipoles?

and if so how would the structure be?

Yes and yes.

Since electric charges are mono-polar, electric hexapoles and any other number, configuration and arrangement of poles is possible. There is no standard configuration called a hexapole, however. The only requirement is that you have equal numbers of positive and negative charges; three each in this case.

One simple configuration for an electric hexapole is a hexagon with the charges positioned at the hexagon's vertices and where the charges alternate in polarity: + - + - ... as you go around. But this is only one of an infinite number of configurations using six charges.

just did a google and found the multipoles should be of order 2n

No idea why, (lazy to understand pure sciences.)

thank you for answering, the truth is I've been given an assignment to prove that although multipoles are to be any power of 2 but still my profesor says a hexapole is possible and I need to figure out how.... fact is I don't even know what kind of multipoles we're talking about...so can you tell me where you found this rule? was it about electric dipoles?

you have a smart answer.

it s easy for you and us to make clear what your professor talking about. try to describe what class you are attending?

static electrics or dynamic electric(electromagnetics)?

can you tell what college you are attending? where?

Could see in this book result

http://books.google.co.in/books?id=axnYh8mx0UAC&pg=PA5&lpg=PA5&dq=what+is+electric+multipole&source=bl&ots=9WPrnPLBMQ&sig=yaRBNZyJDti0UjKN8jUuu0NhMKE&hl=en&ei=m2eVSZfeNJSC6gP7-ZGCCQ&sa=X&oi=book_result&resnum=4&ct=result

Chsck back on page 2,3

It says Zeroett order moment - is the electric monopole moment

First order ... Dipole moment

Second Order ... Quadrapole moment ...

Hope it helps

electric? electrostatic? magnetic?

If in a motor: the pole configuration is electromagnetic, and these come in pairs - as magnetic fields have one north and one south and these have to be in alternating order.

If you make from your 3 dipoles a configuration where all are oriented the same way then you only have a 1 stronger dipole.

If you mount the dipoles alternating then you will have a hexapole, in motor terms called a motor with 3 pole-pairs.
