- electromagnet
- a device that is magnetized by current electricity is called an electromagnet.
- magnetic field
- magnets are surrounded by a magnetic field, an invisible area where the forces of magnetic attractionor repulsion can be detected.
- series circuit
- in a series circuit, there is only one path along which current electricity can flow.
- current electricity
- the flow of an electric chatge throgh a circuit called current electricity.
- static electricity
- static electricity is the buildup of a positive or negitive electric charge on a material's surface.
- resistors
- resistoors lower the amount of electric charge that flows through a device.
- induced charge
- an induced charge is a static charge caused by the presence of an object that itself has a net positive or negitive charge.
- parallel circuit
- in a parallel circuit, there are multiple paths along which current electricity can flow.
- generator
- a generator is a device that converts mechanical energy-supplied by a hand crank, turbine, magnets, or motors-into electricity.
- electricity
- electricity refers to the movement and transfer of the energy of charged particles.
