You asked: How do you make a motor with a battery?

How do you make a motor work with a battery?

Place the wire over the motor.

Take your wire and place it over the battery. As long as you have a section of wire touching the side of the magnet, and a section of wire touching the positive side of the battery, your wire should spin. The current in this homopolar motor flows in the presence of a magnetic field.

How do you start a motor without a battery?

Get a few people to help push the car, push the clutch all the way down and put it into the second gear (do not release clutch just yet). Begin pushing the car and once it has gathered some speed – pop the clutch and the engine should start, and the car’s alternator should start charging the battery again.

Can a motor charge a battery?

Charging a BatteryEdit

The motor must be able to produce enough voltage to charge the battery. For example if the rated voltage of the battery is 5 V then the motor must be able to produce at least 5 V. It also must be able to generate enough current so that the time required to charge the battery is lowered.

Will a 9v battery power a 12v motor?

If you want to spin a big motor, the battery voltage will sag because of the battery’s internal resistance. … In principle, it’s probably possible to run a 12V motor on 9V — it’ll just run slower and with much less torque.

Can a motor run without a battery?

Yes, an automobile can run without a battery, if the alternator is large enough to support all of the electrical needs. However, it’s starting the automobile that would be much more convenient in life if one had a battery.

Will a Jump Starter start a dead battery?

In addition to jump starting a dead battery, portable battery jump starters also come with USB connections to charge all of your devices, important for emergencies and keeping the kids entertained. Some are even equipped with built-in air compressors to fill up tires that are low on air.

Does Kick Start need battery?

These run and start without a battery/dead battery. When you do a kick-start, the alternator runs for that short period. But the issue with the alternator is that it doesn’t produce a constant voltage. Many devices in the electric circuit (including ECU) need a constant voltage (without spikes) to work properly.

Can you use an alternator as a motor?

The humble automotive alternator hides an interesting secret. Known as the part that converts power from internal combustion into the electricity needed to run everything else, they can also themselves be used as an electric motor.

Can you charge a car battery by spinning the alternator?

When the alternator is charging, it takes 3-6 hp to be able to spin it.

How much power does it take to spin an alternator?

How much power does it take to run an alternator? An alternator typically takes about 1 HP (horse power) for every 25 amps of power generated. So, a 100 amp alternator will require about 4 HP at full output. Most alternators do not operate at full output for very long.

How does a simple motor works?

This simple electric motor works by the magnetic force F = IL x B. The current goes around the coil so that it points one direction in one end of the loop and in the other direction at the other end of the loop. The magnetic field at both of these spots points in the same direction.

What is a simple motor?

The basic idea of an electric motor is really simple: you put electricity into it at one end and an axle (metal rod) rotates at the other end giving you the power to drive a machine of some kind. … When an electric current starts to creep along a wire, it creates a magnetic field all around it.

What material do you collect to prepare a simple electric motor?


  1. D battery.
  2. Insulated 22G wire.
  3. 2 large-eyed, long, metal sewing needles (the eyes must be large enough to fit the wire through)
  4. Modeling clay.
  5. Electrical tape.
  6. Hobby knife.
  7. Small circular magnet.
  8. Thin marker.
