Electromagnetism
A temporary magnet created by passing an electric current through a coil of wire, producing a magnetic field around the coil.
What is Electromagnet?
A flow of electric charge in a single, constant direction within a circuit.
What is Direct Current?
A material that allows the flow of electric current due to the mobility of charged particles, such as electrons, within the material.
What is Conductor?
The unit of electrical resistance in a circuit, symbolized by the Greek letter omega (Ω), measuring the opposition to the flow of electric current.
What is Ohm?
The unit of electrical potential difference, indicating the measure of electrical force that drives the flow of current in a circuit.
What is Volt?
An area surrounding charged particles where other charged particles experience a force.
What is electric field!
Electric charge that regularly changes direction in a circuit, typically oscillating between positive and negative values.
What is Alternating Current?
A material that resists the flow of electric current, preventing the movement of charged particles and minimizing electrical conductivity.
What is Insulator?
An electrical component that opposes the flow of electric current in a circuit, limiting the amount of current that can pass through.
What is Resistor?
A circuit configuration where multiple pathways exist for the flow of electric current, allowing current to follow more than one route.
What is Parallel Circuit?
The points on a magnet where the magnetic field is concentrated and where the magnetic forces are strongest.
What is Magnetic Poles?
Devices that modify the voltage of an alternating current; step-up transformers increase voltage, while step-down transformers decrease voltage.
What is Transformers (Step Up and Step Down)?
The electrical force or voltage that causes charged particles to move within a circuit, representing the energy difference between two points.
What is Potential Difference?
The electrical potential difference between two points in a circuit, representing the force that drives the flow of electric current.
What is Voltage?
A circuit configuration where components are connected in a single pathway, so the same current flows through each component in sequence.
What is Series Circuit?
Small regions within a magnetic material where atomic magnets align to produce an overall magnetic effect in the material.
What is Magnetic Domain?
The process by which a changing magnetic field induces an electric current in a conductor, according to Faraday's law of electromagnetic induction.
What is Electromagnet Induction?
A device that converts mechanical energy into electrical energy by inducing a flow of electrons through the movement of a conductor within a magnetic field.

What is Power?
Various devices and elements such as resistors, capacitors, inductors, and other electrical elements that form part of an electrical circuit, contributing to its functionality.
What is Parts of a Circuit/Circuit Components?
The region around a magnet or a current-carrying conductor where magnetic forces are exerted on other magnets or moving charges.
What is Magnetic Field?
The overall opposition to the flow of electric current in a circuit, combining the effects of individual resistances to represent a single resistance value.
What is Equivalent Resistance?
A machine that converts electrical energy into mechanical energy, typically by utilizing the magnetic forces generated by a current-carrying conductor in a magnetic field.
What is Motor?
