Question

A 28 turn coil with average diameter of 0.02 m is placed perpendicular to a magnetic Feild of 8000T .If the field changes to 3000T in 4s,what is the magnitude of induced emf?

Answer 1

Answer:

magnetic field of flux density 10T acts normal in a coil of 50 turns having 100cm2 area. The e.m.f induced if the coil is removed from magnetic field in 0.1 second is.

Answer 2

Answer:

hell plz follow me plz mark as brainlist

Explanation:

A 70 turn coil with average diameter of 0.02 m is placed perpendicular to magnetic field of 9000 T. If the magnetic field is changed to 6000 T is 3s, what is the magnitude of induced emf.
