One variable that needs to be controlled is the number of coils of the electromagnet as the more coils the stronger the magnetic force, so the same number of coils should be used for each test.
A Controlled Variable is a variable that will stay the same. An Uncontrolled Variable is a variable that stays at random during testing.
"Controlled Variable" or "Manipulated Variable"

controlled variable is something that is controlled by the independent variable
Manipulated Variable, Responding Variable, And Controlled Variable.
controlled variable is something that is controlled by the independent variable
A controlled variable is a setting where the dependent variable is not controlled by the independent variable. For example, if you were trying to measure the rate of movement in an organism in highly salty concentrations, a controlled variable would include the organism in an environment with no salt at all.
A Controlled Variable is a variable that will stay the same. An Uncontrolled Variable is a variable that stays at random during testing.
The controlled variable is the one that you chose to change while the dependant is the variable that changes because it is effected by the controlled variable
