Unit 13

6. A vector field that determines the magnetic force exerted on moving electric charges, electric currents, or magnetic materials.
7. The principle that describes the relationship between a changing magnetic flux and the induced emf in a system, expressed as ε = -∆ΦB/∆t.
9. The tendency of a conductor to oppose a change in electrical current.
10. The opposition to the flow of electric current in a circuit, measured in ohms (Ω).
12. A circuit element that dissipates electrical energy and opposes the flow of current, characterized by resistance R.
13. A circuit element that stores electrical energy in an electric field between two conducting plates.

1. A coil of wire wound in a tight, helical pattern that produces a uniform magnetic field when current flows through it.
2. The force exerted on a moving charged particle or current-carrying conductor in the presence of a magnetic field.
3. A circuit containing only a capacitor and an inductor that can oscillate, exchanging energy between electric and magnetic fields.
4. The measure of the total magnetic field passing through a surface, calculated as the dot product of the magnetic field vector and the area vector.
5. A property of a material that describes how easily a magnetic field can be established within it; affects the inductance of a solenoid.
8. A circuit containing a resistor and inductor in series with a power source, where current changes are governed by both resistance and inductance.
11. A circuit element that stores electrical energy in a magnetic field and opposes changes in current.
