|---|---|
| a fundamental property that leads to the electromagnetic interactions among particles that make up matter | Electric charge |
| electric charge at rest | static electricity |
| a material in which charges can move freely | electrical conductor |
| a material in which charges cannot move freely | electrical insulator |
| an element or compound that conducts electric current better than an insulator does but not as well as a conductor does | semiconductor |
| the rate at which electric charges pass a given point | electric current |
| in physical science the opposition presented to the current by a material or device | resistance |
| the amount of work to move a unit electric charge between two charge between two points | voltage |
| a set of electrical components connected such that they provide one or more complete paths for the movement of charges | electric circuit |
| a circuit in which the parts are joined one after another such that the current in each part is the same | series circuit |
| a circuit in which the parts are joined in branches such that the voltage across each part is the same | parallel circuit |
| any material that attracts iron ot materials containing iron | magnet |
| the force of attraction or repulsion generated by moving or spinning electric charges | magnetic force |
| one of two points such as the ends of a magnet that have opposing magnetic qualities | magnetic pole |
| a region where a magnetic force can be detected | magnetic field |
| the interaction between electricity and magnetism | electomagnetism |
| a coil that as a soft iron core and that acts as a magnet when an electric current is in the coil | electromagnet |
