Asingle-turn circular loop of wire of radius 5.0 cm lies in a plane perpendicular to a spatially uniform magnetic field. during a 0.05480.0548-\text{s}s time interval, the magnitude of the field increases uniformly from 200 to 300 mt. determine the magnitude of the emf induced in the loop.

Induced EMF,

Explanation:

Given that,

Radius of the circular loop, r = 5 cm = 0.05 m

Time, t = 0.0548 s

Initial magnetic field,

Final magnetic field,

The expression for the induced emf is given by :

= magnetic flux

So, the induced emf in the loop is 0.0143 volts. Hence, this is the required solution.

the duration of a photographic flash is related to an rc time constant, which is 0.100 μs for a certain camera.

myth. it was once thought that animals, including cats and dogs, could only see in black and white. however, scientists have proven this to be a myth. in all animals, including humans, the perception of colour is determined by the presence of cells in the eye called cone photoreceptors.
