Current = Voltage/Resistance If you add resistors to the circuit (in series), current will decrease.

Voltage= Current X Resistance Hence, Current is Voltage/Resistance so if you increase Resistance Current will Decrease.

Well, the easiest thing to do would be to use a battery with a lower voltage, which would reduce the current (because of the formula I = V/R, a decrease in voltage causes a decrease in current). Or, you could place a resistor in series with the motor, to increase the resistance of the circuit (I = V/R again, an increase in resistance causes a decrease in current).

you need to put a resistor…and you also have an inductor to induce current and ofcoures you must know the EMF (ELECTROMAGNETICFORCE) or simply the voltage of your supply…to decrease the flow of the current you must have a resistor with big resistance….

A rheostat is something you can plug into and then modify the current. Sorta like a dimmer switch. I use one on my soldering iron.
