Electromagnetic Field Theory Two identical circular coils, one closed and another is little split (not enclosed) are placed in an uniform magnetic field which decrease at a constant rate. If the plane to the coils are perpendicular to the field which of the following statements is true? Joule heating does not occur in each of the coils. An emf is induced in split coil. An emf is induced in both coils. Equal joule heating occurs in both coils. Joule heating does not occur in each of the coils. An emf is induced in split coil. An emf is induced in both coils. Equal joule heating occurs in both coils. ANSWER DOWNLOAD EXAMIANS APP
