Electricity and Magnetism
- F3.1 describe the properties of magnetic fields in permanent magnets and electromagnets (e.g., the three-dimensional nature of fields, continuous field lines, fields around currentcarrying conductors and coils).
▹
- F3.2 explain, by applying the right-hand rule, the direction of the magnetic field produced when electric current flows through a long straight conductor and through a solenoid.
▹
- F3.3 distinguish between conventional current and electron flow in relation to the left- and right-hand rules.
▹
- F3.4 explain Ohm’s law, Kirchhoff’s laws, Oersted’s principle, the motor principle, Faraday’s law, and Lenz’s law in relation to electricity and magnetism.
▹
- F3.5 describe the production and interaction of magnetic fields, using diagrams and the principles of electromagnetism (e.g., Oersted’s principle, the motor principle, Faraday’s law, Lenz’s law).
▹
- F3.6 explain the operation of an electric motor and a generator, including the roles of their respective components.
▹
- F3.7 distinguish between alternating current (AC) and direct current, and explain why alternating current is presently used in the transmission of electrical energy.
