What happens if an electromagnets ecectricity is turned off?
When the electricity is turned off in an electromagnet, the magnetic field it generates disappears, causing the magnetism to cease. This means it will no longer attract or repel other magnetic objects in its vicinity.
What happens when a screw is turned?
When a screw is turned, it moves in a linear direction along its axis due to the helical thread design. This action creates a force that either fastens or unfastens the screw from the object it is being inserted into. Turning the screw clockwise tightens it, while turning it counterclockwise loosens it.
What happens to an electric current at a switch?
At a switch, the electric current can be opened (turned off) or closed (turned on) depending on the position of the switch. When the switch is opened, the circuit is broken, and no current flows. When the switch is closed, the circuit is complete, and current can flow through the circuit.
What happens to the powder when the light was off?
If the powder is luminescent or phosphorescent, it will glow in the dark for a period of time after the light is turned off due to stored light energy being slowly released. If the powder is just regular powder without any special properties, it will remain dark once the light is turned off.
What happens to particles inside hot air balloons when the heater is turned on?
When the heater is turned on inside a hot air balloon, the air inside the balloon gets heated, causing the particles to move faster and spread apart. This lowers the density of the air inside the balloon, making it lighter than the surrounding cooler air, which allows the balloon to rise.
