First, single-choice questions 1. The following description of the magnetic flux, the correct is: () A. A magnetic flux passing through a certain area is zero, indicating that the magnetic field intensity in this area must be zero. B. The area where the magnetic induction intensity is zero passes through The magnetic flux of the coil must be zero. C. The magnetic fluxes passing through the two coils are equal, then the magnetic induction must be equal in the two regions where the two coils are located. D. The same coil must be equal in magnetic flux no matter how it is placed in a uniform magnetic field. 2. Regarding the uniform magnetic field, the following statement is correct: () A. The magnetic induction intensity is equal to the uniform magnetic field. B. In the uniform magnetic field, the magnetic induction intensity of each point
