Electromagnetism Equations Explained For HSC Physics
HSC Physics Syllabus
- analyse the interaction between charged particles and uniform magnetic fields, including: (ACSPH083)
– acceleration, perpendicular to the field, of charged particles
– the force on the charge `F=qv_(_|_)B = qvBsintheta`
- investigate qualitatively and quantitatively the interaction between a current-carrying conductor and a uniform magnetic field `F=lI_{_|_}B=lIB\sin\theta` to establish: (ACSPH080, ACSPH081)
- analyse the interaction between two parallel current-carrying wires `F/l=\mu_0/(2\pi) (I_1 I_2)/r` and determine the relationship between the International System of Units (SI) definition of an ampere and Newton's Third Law of Motion.
- investigate the operation of a simple DC motor to analyse:
-
– the functions of its components
– production of a torque `\tau = nIAB_(_|_) sin \theta`
– effects of back emf (ACSPH108)
