Transcript

hi I'm Steve Jones I'm going to tell you how to make a nine volt electric motor well there are two main components one of them is a pair of field magnets now you can't make those so what you have to do for these is you have to go buy them in the shop they're usually ceramic magnets they're flat and something like a centimeter thick and they have a ...

Questions & Answers

Q: What are the main components needed to build a 9-volt electric motor?

The main components are field magnets (ceramic magnets with North and South Poles) and a coil wrapped around a former connected to a 9-volt battery through a commutator.

Q: How is the coil positioned between the field magnets for the electric motor to function?

The coil is placed between the magnets with the bare wire ends connected to the battery via a commutator, ensuring proper alignment for rotation when flicked.

Q: What is the purpose of the commutator in the 9-volt electric motor?

The commutator changes the current direction every half rotation, allowing the motor to continue rotating in the magnetic field produced by the magnets.

Q: What role does the coil play in the functionality of the 9-volt electric motor?

The coil, when connected to the battery and positioned correctly between the magnets, generates a magnetic field that interacts with the field magnets to produce rotation.

Summary & Key Takeaways

• Field magnets and a coil are essential components for building a 9-volt electric motor.

• The field magnets must be purchased and are typically ceramic with a North and South Pole.

• The coil is wrapped around a former and connected to a 9-volt battery through a commutator for rotation.
