(a) Explain why increasing the number of loops is initially beneficial. (b) Explain why there is a limit to increasing the number of loops. In other words, why is it that at some point, increasing the number of loops does not increase the speed at which the motor spins.
I made a simple motor using a copper coil wire, battery and a magnet and I would like help on these last questions. Thanks :)
Engineers often find that while increasing the value of a variable may be beneficial to the desired outcome, a critical point is often reached where increasing the value of that variable any further actually works against them. With a simple DC motor, the number of loops in the rotor acts as such a variable.
