Coulomb's Law - ANSWERThe force that two charges at rest exert on each
other is directly proportional to the product of the charges and inversely
propertional to the square of the distance between them.
Ohm's Law - ANSWERThe voltage across a conductor is directly proportional
to the current through it provided that physical conditions such as
temperature is kept constant.
Electric field strength - ANSWERForce per unit charge in an electric field
experienced by a charge placed at that point.
alpha particle - ANSWERA helium nucleus with a charge of two protons
Solenoid - ANSWERCoil of many loops of wire that are wound to look like a
cylinder.
Right Hand Rule - ANSWERIf the thumb is in the direction of the current, then
the curled fingers will be in the direction of the magnetic field around a loop.
, Right Hand Rule in a Solenoid - ANSWERIf the curled fingers are in the
direction of the current, the the thumb will be in the direction of the
magnetic field inside a solenoid.
Galvanometer - ANSWERA measuring instrument tha detects and measures
very small current and voltage.
Magnetic Flux(θ) - ANSWERThe total magnetic field thst passes through an
area such as a loop. It's a scalar quantity, with SI units weber(Wb).
Magnetic flux linkage - ANSWERIt is linked with a particular object such as a
loop or solenoid.
Magnetic flux density (B) - ANSWERIs a measure of strength and direction of
the magnetic field. It's a vector quantity, with SI units tesla(T).
Faraday's Law of Induction. - ANSWERThe magnitude of the induced emf
across the ends of a conductor is directly proportional to the rate of change
of the magbetic flux linkage with the conductor.
Inverse square law - ANSWERThe magnitude of a physical quantity that obeys
this law is inversely proportional to the square of the distance from the
source.
Electric field - ANSWERIs a region of space in which an electric charge
experiences a force.
