What two things are needed to make an electromagnet?
To make an electromagnet, you need a coil of wire and a source of electrical current. When the electrical current flows through the wire coil, it creates a magnetic field, turning the coil into a magnet.
What 3 things do you need for an electric current?
To have an electric current, you need a source of voltage (such as a battery or power supply), a complete electrical circuit (includes wires and components), and a conductive material (such as copper wire) for electrons to flow through.
Why does an electrical cord need both a conductor and a insulator?
The conductor carries the electrical current while the insulator prevents the current from leaking out and causing electric shocks or fires. Both components are necessary for the safe and efficient transmission of electricity.
Why do people have to turn on and off the flow of electrical current?
Turning electrical devices on and off helps conserve energy and prevent unnecessary use of electricity. It also helps protect devices from damage due to power surges or overheating. Additionally, controlling the flow of current allows for greater safety in handling electrical equipment.
How does a coil of wire create a electrical current?
When a coil of wire is placed in a magnetic field and the magnetic field is changing (e.g. from a moving magnet or changing current), it induces an electrical current in the wire through electromagnetic induction. The changing magnetic field causes electrons in the wire to move, creating a flow of electrical current.
What three things do you need for electric current?
protons,neutrons and electrons

What are three things you need to make an electromagnetic?
Three things you need to make an electromagnetic are a magnetic field, an electric current, and a conductor or coil of wire. When an electric current flows through the conductor, a magnetic field is created around it, resulting in an electromagnetic effect.
What are two things required to make electric current flow in a circuit?
you need an electrical supply and a load. nice and simple.
What is the car current amp's consumptions need?
The current use all depends on what electrical fixtures or accessories are being used.
What are three things that need to be cleaned by water?
the three things that need to be cleaned from water are chemicals,germs
Why are there fuses for the transmission?
Because all electrical circuits need over-current protection.
How do you know if there a current?
Do you mean water current? Do you mean electrical current? I'm not sure really what you're asking. You need to be specific. Either way, don't stick an electrical wire into water to check the current as you may die. It's not a healthy test.
Does electrical current increase as voltage increases?
Electrical current generally increases as voltage increases due to a need for increased capacity. This is directly controlled from the transmission side but varies based on the overall load.
What are the three things electronic hardware devices need in order to function?
An electrical system to provide power It needs software to instruct the device A method for the CPU to communicate with the device
Does The higher the amperage equal more electrical power?
Not necessarily. Amperage (current) is just one component of electrical power. Power is the product of voltage and current. To calculate power, you need both voltage and amperage.
