Find an expression which shows the conversion of mechanical energy in to electrical energy through magnetic induction.
I'm a second year physics undergraduate, and currently learning using Vanderlinde's Classical Electromagnetics Theory. One of the books question I found is:
2-12 Show that the quadrupole term of the multipole expansion of the potential can be written
"V_{3}=\\frac{1}{8\\pi\\varepsilon_{0}}\\sum q_i\\vec{r}^{\\left(i\\right)}\\cdot \\vec{\\nabla }\\left[\\vec{r}^{\\left(i\\right)}\\cdot \\vec{\\nabla }\\left(\\frac{1}{r}\\right)\\right]"
How should I solve this? Where do I start?
List the electromagnetic wave according to their penetration power
An ion with a +1 charge is fired through a 150 mT magnetic field as shown below. The particle is moving to the right at a speed of 7.1e+6 m/s. What is the magnitude and direction of the force on the charge?
Find electrical potential due to Ring at a point P. The point P is lies at distance Z from the origin along the Z- axis.
Make a situation in which a dipole is placed along Z-axis at origin. Find electrical potential at a point P. The point P is lies at distance Z from the origin along the dipole axis.
Consider each of the electric and magnetic field orientations given next.In each case, draw the figure and identify what is the direction and propagation of the wave? For vectors x,y,z are the unit vectors of Oxyz Cartesian coordinate:
