When a magnet is brought near a light bulb, the magnetic field interacts with the electric current flowing through the filament, causing a force to be exerted on the filament. This force can make the filament move or vibrate, resulting in changes in the brightness or flickering of the light bulb.

What three objects make a light bulb glow?
A light bulb requires a power source (electricity), a filament (usually made of tungsten) within the bulb, and a vacuum or inert gas environment in the bulb to prevent oxidation of the filament. When electricity flows through the filament, it heats up and emits light, causing the bulb to glow.
What transformation did electrical energy undergo to make the bulb glow?
The electrical energy was transformed into light and heat energy in the light bulb, causing it to glow. This transformation occurs when the electricity passes through the filament in the bulb, producing light and heat as a result of the filament's resistance to the flow of electricity.
What make a light bulb glow?
A light bulb glows when an electric current passes through the filament inside, which heats up due to resistance and emits light. The filament is usually made of tungsten, a material that can withstand high temperatures without melting.
Can you use a copper wire to make a filament of an electric bulb?
No, copper wire cannot be used to make the filament of an electric bulb as copper wire has very low resistance. Therefore, the bulb will not glow if current is passed. It would also melt - the filament has to be white-hot to be any use!
What makes a light bulb shine brighter?
Increasing the amount of electrical current flowing through the bulb's filament will make it shine brighter. Additionally, using a higher wattage bulb or a bulb with a higher lumen output will also produce a brighter light.
Is resistance in the filament of a lamp essential or not?
Yes, the resistance of the filament of a light bulb is what generates enough heat to make the filament glow and produce light.
You are using a bulb whose filament is broken will the bulb glow when connected to battery give reason?
No, the bulb will not glow when connected to a battery if the filament is broken. The filament is the part of the bulb that heats up and produces light when electricity passes through it. If the filament is broken, there is no path for the electricity to flow through and generate light.
What year did Louis Lattimer make the filament for the light bulb?
2008
What type of filament will make the light bulb turn on for a longer period of time?
The filament is nothing to do with the light turning on, that is controlled by the switch.

How does a battery make a light bulb 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.
What element make up light bulb filament?
The filament in a light bulb is typically made of tungsten, due to its high melting point and resistance to heat. Other materials, such as carbon or other metals, can also be used in some types of light bulbs.

What was Thomas Edison's challenges when inventing the light bulb?
Thomas Edison faced challenges such as finding the right material for the filament that could withstand high temperatures without burning out quickly, creating a vacuum inside the bulb to prevent the filament from oxidizing, and designing an efficient electrical distribution system to make the light bulb practical for widespread use.
