A coil is wrapped with 332 turns of wire on the perimeter of a circular frame (of radius 30 cm). Each turn has the same area, equal to that of the frame. A uniform magnetic field is directed perpendicular to the plane of the coil. This field changes at a constant rate from 29 mT to 56 mT in 63 ms. What is the magnitude of the induced average E in the coil, over the time interval 63 ms during which the field changes

Explanation:

From the question we are told that:

Number of Turns

Radius

Field Change

Time

Generally the equation for Magnetic Field is mathematically given by

Generally the Flux at 332 turns is  mathematically given by

Generally the equation for Area of coil is mathematically given by

Since

Therefore

Generally the equation for emf Magnitude is mathematically given by

im not to sure what it is

cell differentiation  is how generic embryonic  cells  become specialized  cells. this occurs  through a process called gene expression. gene expression is the specific combination of genes that are turned on or off (expressed or repressed), and this is what dictates how a  cell  functions.
