Study the scenario.

a magnetic field is generated when using an electromagnet. the events that occur to create the magnetic field are listed below.

the magnetic domains align inside the piece of metal.
close the circuit so a current flows through it.
wrap a wire to create loops around a piece of metal, such as iron.
the magnetic field is generated inside the loops.
what is the correct order of events?

c, a, b, d
b, a, d, c
c, b, d, a
a, c, b, d
