A solenoid is a coil of wire that produces a magnetic field when carrying an electric current. The strength of the magnetic fiel
d
produced by a solenoid can be increased in two basic ways: increasing the number of loops in the solenoid or increasing the
amount of current running through the solenoid. A solenoid's magnetic field can be increased to an even greater degree by wrapping
the wire around a material that can be magnetized. Four solenoids are shown below.

Solenoid A
Copper Wire Only
Current: 6 amps
Solenoid B
Copper Wire Only
Current: 8 amps

Solenoid C
Copper Wire + Iron Core
Current: 6 amps
Solenoid D
Copper Wire + Iron Core
Current: 8 amps
Based on the strength of the magnetic fields they produce, arrange the solenoids from strongest to weakest.
