Describe in details three practical applications for magnetostatic.

I need to develop a VHDL code for a FPGA basys 3, 4 digit 7 segment display. So when binary 0, 1 ,and 2 are inputted the display says bad. When binary 3,4,5,6, the display says good.

Select the correct answer:

1.One of the following is the origin of a magnetostatic field:

   a. 2 electric charges

   b. direct current on a wire

   c. constant electric field

   d. disc loaded

2. It is known that the self-induced electromotive force in a long selenoid, through which a variable current flows with time, depends on the factors that are described below, indicating which is the most influential:

   a. the number of turns

   b. the length of the selenoid

   c. current variation
