Magnetism
What is it called when an area around a magnet, you can feel magnetic forces?
Magnetic Field(s).
What is a closed circuit?
A complete, uninterrupted path for electrical current to flow.
What is copper?
A type of metal that is used for electricity.
Energy can power things like lights, computers, and phones
TRUE!!!
What is iron?
This metal object is commonly used as the core in an electromagnet to strengthen its magnetic field.
What is an electric circuit?
A closed loop that allows electric current to flow continuously.
What is an electromagnetic field?
When electric current flows through a wire wrapped around a metal core, it creates this type of magnetic field.
What is 3 words that describe circuits?
Conductor, Electricity, and Path
What is switching or activating?
This is the term for the process of turning an electromagnet on or off by controlling the flow of electricity.
What is a switch used for in a circuit?
A switch is used to open or close a circuit, allowing you to turn devices on or off and control the flow of electricity.
Why is it important that electrical wires are coated with rubber or plastic? Explain how this relates to the properties of conductors and insulators.
Electrical wires are coated with rubber or plastic because of crucial safety measure and these materials are insulators. Which means they do not allow electricity to flow through them.
What is a relay?
This device uses an electromagnet to control the movement of mechanical parts in machines and industrial equipment.
What is a series circuit?
This type of circuit has components connected in a single path, so the current has only one route to follow.
Explain the difference between a conductor and an insulator, and provide two examples of each.
A conductor is a material that readily allows electrical current to flow through it. An insulator is a material that resists the flow of electricity.
Conductor: Copper & Silver
Insulator: Rubber & Plastic
Explain how increasing the number of coil turns and the current affects the strength of an electromagnet.
Increasing the number of turns in the coil and the electric current flowing through it both increase the magnetic field strength of the electromagnet.
