I've attached the .pdf from which I have questions.
After it says "Take the square of the numerator" halfway down the page, there is an equation that lists vector components with hats and arrows at the same time, and the arrow on other vectors. Can someone help explain the difference to me...
Can someone help me with the conversion of this equation to Cartesian coordinates:
[SIZE="4"]2cosθr + sinθθ
(Due to formatting limitations, I just made the r_hat and theta_hat components bold-faced)
I know the answer ought to be -(3y2)/[(x2+y2)+1] but I've tried every variation of the 3 main...
Thanks for the reply chiro! I imagine I'll be here a few more times before my thesis is done... M is a function of H actually, and H is a function of the vector r, representing the radius.
The equation as initially written, describes the force on a particle by a magnetic field. H is the...
I was reading a paper and came across this equation:
Fmagnetic=μ0(M<dot>∇)H
Is this the correct expansion below? (I'm not too experienced with vectors operating on the gradient operator)
Fmagnetic=μ0[(Mx ∂H/∂x)i + (My ∂H/∂y)j + (Mz ∂H/∂z)k]

My reasoning partially comes from...
