Answer:
C, D, B and A.
Explanation:
Electromagnet in option C is strongest because it has an iron core and the largest current as compared to other solenoids, following by D and then B whereas solenoid A is the weakest because of the absence of an iron core and has the smallest current. Solenoid having iron core is the strongest solenoid because the core produces more strong magnetic field as compared to no iron core.

Using our normal decimal numbering system, the base of a number system, for example 8, tells us two things
1. Each
digit is an integer that uses numbers from 0 to 7. There are 8 possible values
for a digit
2. We
multiply each digit by a power of 8 depending on the position of the digit.
If we use number 112 to (base 8), then;
<span>(1 x 8 to the power of 2)
+ (1 x 10 to the power of 1) + (2 x 8 to the power of 0). </span>
