Faraday's Law Faraday's Law connects the?rate?of change of?flux linkage?with induced e.m.f It is defined in words as: The magnitude of the induced e.m.f is directly proportional to the rate of chan...
Induced Emf Electromagnetic induction is a phenomenon which occurs when an?e.m.f.?is induced when a conductor moves through a magnetic field When the conductor cuts through the magnetic field lines...
Emf, Magnetic Flux & Magnetic Flux Linkage Electromagnetic Induction When a conducting wire moves through a magnetic field, a?potential difference?is created along the wire If the wire is part ...
Forces on Charges & Masses The electric field strength equation can be rearranged for the force?F?on a charge?Q?in an electric field?E: Where: F = electrostatic force on the charge (N) Q = char...
Forces & Inverse-Square Law Behaviour The gravitational force between two bodies outside a uniform field (for example, between the Earth and the Sun) is defined by Newton’s Law of Gravitation w...
Orbital Motion, Speed & Energy Since most planets and satellites have a near circular orbit, the gravitational force?FG?between the sun or another planet provides the?centripetal force?needed t...
Escape Speed To escape a gravitational field, a mass must travel at the?escape velocity This is dependent on the mass and radius of the object creating the gravitational field, such as a planet, a ...
Potential in a Charged Sphere The?electric potential?in the field due to a?point charge?is defined as:Where: V?= the electric potential (V) Q?= the point charge producing the potential (C) ε0?=?per...
