Aconstant magnetic field passes through a single rectangular loop whose dimensions are 0.393 m x 0.549 m. the magnetic field has a magnitude of 2.29 t and is inclined at an angle of 65.1° with respect to the normal to the plane of the loop. if the magnetic field decreases to zero in a time of 0.500 s, what is the magnitude of the average emf induced in the loop?

The average induced emf in the rectangular loop is 0.41V

Explanation:

We can resolve this problem through the expression for induced emf in the loop.

This expression is,

Where

is the electro magnetic field

B = Magnetic field

A= Area

dt = change in time.

We have all of this values, because the dimension of the object are enough to calculate the Area .

The average induced emf in the rectangular loop is 0.41V

It is because there is a loop between state 1 and state 2. The given data corresponds from B1 to B2. The total change would be measured by (B2-B1), but B2 is zero. So you get (-B1)

the device is called “ rocket engine”

a. vertically

explanation:

i tried it and took the test

if im wrong then we have different tests
