By attaching a fan in the dynamo and rotating the fan and connecting one end of wire in the dynamo and another end in a bulb which helps in glowing of bulb by using the power of dynamo.

No, a copper penny cannot make a light bulb glow on its own. The electrical conductivity of copper is too low to generate enough current to power a light bulb. Additional components, such as a power source and circuit, would be needed to make the light bulb glow.
A ultra violet light will make things glow.

The flow of electrons from the battery flow through the filament in the bulb causing it to get hot and glow thus producing light.

To make light bulbs glow dimmer, I reduced the amount of electricity flowing to them by using a dimmer switch or a lower wattage bulb. This decrease in electricity causes the filament in the bulb to emit less light, resulting in a dimmer glow.
To make light bulbs glow brighter, you can increase the voltage supply to the bulb. This will cause more current to flow through the filament, resulting in a brighter glow. Be cautious not to exceed the recommended voltage rating of the bulb, as this can lead to overheating and damage.

This is usually done by passing an electrical current through the wire.
Push a galvanised nail and a copper coin (or bare copper wire, copper nail) into a lemon or a potato. Connect two wires from a torch bulb. The bulb should glow to prove that electricity is flowing.
