I have constructed several using a bar magnet attached to a shaft at it's center point, so it is balanced on the shaft. Wind two coils around cylindrical steel cores. Construct a frame to support the shaft with bar magnet, and the two coils. The shaft needs to be supported so that it spins freely, and the coils need to be mounted so they both align simultaneously with the opposite poles of the bar magnet - they are 180 degrees from one another with respect to the shaft and bar magnet, and the steel rods that make up the cores of the coil are in alignment with the bar magnet. A wire end of one of the coils is connected to one end of the other coil so the coils wind in the same direction as if one coil was a continuation of the other, interrupted in the middle by the shaft and bar magnet. The opposite ends of the coils complete a circuit through an electrical load. If you spin the shaft, you should be able to read an a.c. (alternating current) voltage with a meter, across the two ends of the conductors. The more turns on each coil produces higher voltage. If you don't read anything, try swapping ends with one of the coils.
You can use LEDs at the leads and if you have enough voltage, you can light the LEDs as well as convert the a.c. voltage to d.c. voltage.

∙ 11y agoTo make a magnet generator is actually very simple. All you need is magnet, preferably strong, some cardboard, a nail and lots of copper wire. You fold the cardboard so it makes a hollow cube or rectangular prism and punch a hole all the way through both sides. This is where the nail will go through. You then attach the magnet to the nail, in the hollow section of the box and wrap all the wire around it leaving to ends trailing off. If you spin the nail (with magnet attached), you are generating an electric current. To see this in action, attach the two trailing wires to a small 1.5-2v light bulb and then spin the magnet. The bulb should light up, depending on the strength of the magnet you used. Hope this helps!

A machine that uses a magnet to make electricity is called?
a generator
How many magnet does a generator have?
At least one. Beyond that it depends on the specific design of the generator.
How can magnet produce current?
Faraday found that a wire passed by a magnet induces a current in the wire. This led to making an electrical generator.
Disadvantage of permanent magnet generator?
since the magnet are place in north and north direction or south and south direction, the magnet will continue to loose it magnetic force of attraction. for more question call me on 2348133605375.
What devices use magnets to create electricity?
An electrical generator. A microphone. A jet engine vibration detector. It has a magnet moving inside a bobbin with wire wrapped around it. An electric guitar pick up. A tape recorder head. A solar powered Sterling engine. The piston is a magnet and it passes through a coil. A few more.
What two items are needed to make a generator?
A wire and a magnet
A machine that uses a magnet to make electricity is called?
a generator
Can a permanent magnet solenoid be modified to work like a permanent magnet linear generator?
yes - need to run electricity through it to make it a linear magnetic generator.
What is a magnet pole in a simple generator?
Induce current in the generator windings.
How many magnet does a generator have?
At least one. Beyond that it depends on the specific design of the generator.
How do you make electricity in space?
The same way you make it on earth. Use either some form of rotating magnet generator or a solar cell.
How is a generator useful?
it uses electricity to create a magnet
What does a generac generator do?
Generac is a brand of generator, what they do will depend on the model you buy. Most models of Generac generators are set to switch on automatically in the case of the a black out but they also have commercial generators for use in business (particularly construction) and RV generators
How does a Generator conductor electricity?
The generator induces a current in a wire using a magnet and a coil of wire. When the drive on a generator is rotated, a magnet inside the generator is spun around. This creates a moving magnetic field inside the generator. Located inside and around the generator is a coil of wires, which lead to a power storage device. As the magnetic field moves around, it induces a current in these wires by pushing the electrons inside the wires. The amount of electricity generated by a generator can be increased by increasing the amount of coils around the magnet, increasing the strength of the magnet, or by simply increasing the speed at which the drive is turned.
Describe the energy transformation that takes place in a generator?
Mechanical energy to electrical energy. A generator consists of a large magnet placed inside a coil of wire. . When the magnet is rotated (mechanical) it impels the electrons in the wire to move(electrical). Conversely, with suitable electrical engineering, when a magnet is placed inside a wire coil and electricity is passed through the wire, it will make the magnet rotate.
In building an electrical generator does the the magnet have to touch the spinning copper or does it not matter?
no, magnet needs to be close to winding, not touching it
How do you make a battery out of a magnet?
You can't. What you could do is build a generator that creates power. You take the magnet past a coil and a small current is generated. Doing so may times and really fast causes more power.
