You decide to build a small generator by rotating a coiled wire inside a static magnetic field of 0.30 t. you construct the apparatus by coiling wire into 5 loops of radius 0.18 m. if the coils rotate at 2.0 revolutions per second and are connected to a device with 120ω resistance, calculate the average power paverage supplied to that device.

0.0153 W

Explanation:

Given

Magnetic Field B=0.3 T

N=5

radius R=0.18 m

flux associated with loop is

and Induced emf is

and let Q be the energy dissipated then

Thus

another example of kinetic energy would be,

kinetic energy   >     moving energy

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.
