what factors influence the performance of electromagnetic induction…
what factors influence the performance of electromagnetic induction systems?
coil
shape of the coil (circular vs square)
orientation of the coil
number of turns in the coil
dimensions of the coil
area through which magnetic field passes
length of the coil
distance between the coil and magnet
alignment
if the magnet is moving through the coil
starting position
will acceleration be constant?
will there just be acceleration due to gravity?
higher or lower?
affect on induced emf
materials
of the magnet
of the coil
conductivity
resistivity
between the magnet and coil
how can different materials block magnetic fields?
core
iron core, no core, different metals, etc
how can materials be quantitatively measured?
what properties can be measured?
induced emf
how can it be measured accurately?
peak emf
average emf
induced current
rms current
Faraday's Law
power output
how is power converted to electrical energy?
output current
output voltage
input current
input voltage
energy loss
how much energy is lost?
what factors lead to loss in energy?
magnet
strength
how can temperature affect strength?
size
shape
speed
orientation of the poles
different applications (what is the system being used for?)
induction cooktops
bicycle dynamos
generators
transformers
