Question

At the end of the previous experiment, aclumsy scientist drops the coil, while still in the magnetic field, and still oriented with its plane perpendicular to the magnetic field, denting it and changing its shape to a semi-circle. The new shape has the same perimeter, but a different area, and it takes 0.036s to deform. What isthe average induced EMF during this mishap

Answer 1

hello your question has some missing parts below are the missing parts

A Circular, 10-turn coil has a radius of 10.7 cm and is oriented with its plane perpendicular to a 0.2-T magnetic field.

answer : 1 volt

Step-by-step explanation:

Determine the Average induced EMF during this mishap

A' = A/2 ( for a semi circle )

where A =
`(\pi r^2)/(2)`

To determine the Average induced EMF apply the relation below

| E | = η *
`(\beta A)/(T)` ----- ( 1 )

Replace A in equation 1 with A =
`(\pi r^2)/(2)`

hence equation becomes : | E | = η * βπr^2 / 2T'

where : T' = 0.0365 , β = 0.2 , η = 10 , r = 0.107

∴| E | = 0.999 ≈ 1volts
