A closely wound rectangular coil of 80 turns has dimensions of 25.0 cm by 40.0 cm. The plane of the coil is rotated from a position where it makes an angle of 37.0° with a magnetic field of 1.30 T to a position perpendicular to the field. The rotation takes 0.0800 s. What is the average emf EMF induced in the coil?
What is the magnitude of the average emf E induced as the coil is rotated?

Induced emf will be equal to 51.76 volt  

Explanation:

We have given number of turns N = 80

Dimension of rectangular coil is 25 cm by 40 cm

So area of rectangular coil

Change in magnetic

Change in time is given dt = 0.08 sec

Induced emf is given by

So induced emf will be equal to 51.76 volt

in simple terms, the principle states that the buoyancy force on an object is equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravitational acceleration, g. this is also known as upthrust.

answer: option c.
