Electricity and Magnetism

Front

What is electricity?

Back

Electricity is the effect of the apparent flow of electrons through a conductor. It is also referred to when talking about using electrical energy to power homes, cars, and other things.

What is electric current?

Back

Electric current is the flow of an electric charge through a conductor, resulting in heat and magnetic fields. Examples include lightning, static electricity discharge, and electricity in power lines.

What is static electricity?

Back

Static electricity is the buildup of an electrical charge in or on the surface of an object. It occurs when electrons transfer from one object to another, causing a charge buildup.

Front

What is electric force?

Back

Electric force is the force of attraction between two electrically charged objects or a charged object and a neutral object. It can cause objects to cling to each other.

What is needed to make an electric circuit?

Back

To make an electric circuit, you need a power source, a path for the electric current to flow through, and a component to consume power, such as a light bulb or motor. A switch can be added to control the flow.

Front

What are conductors and insulators?

Back

Conductors are objects through which an electric current can flow, like metal wire. Insulators are objects through which an electric current cannot flow, like glass, plastic, and rubber.

Front

What is magnetism?

Back

Magnetism is a property of certain materials that allows them to attract or repel other objects with this property. It is generated by magnetic fields or electric currents.

Front

What is an electromagnet?

Back

An electromagnet is created when an electric current flows through a wire wrapped around a magnetic metal core, like iron or steel, creating a magnetic field. The magnetism fades when the current is turned off.

Front

What is a magnetic field?

Back

A magnetic field is the area around a magnet where magnetic forces can be observed. It is represented by field lines that show the direction and strength of the magnetic force.
