How does the magnetic energy compare with the electrostatic energy stored in a capacitor? |
|
Answer» Solution :The magnetic energy per unit VOLUME is `mu_(B)=(U_(B))/(V)` [where V is volume that contains flux) `=(U_(B))/(Al)=(B)/(2mu_(0)).....(1)` We have already obatined the relation for the electrostatic energy stored per unit volume in parallel plate capacitor. `u_(E)=1/2 epsi_(0)E^(2)....(2)` In both the cases energy is proportional to the square of the field strength. |
