ELECTROMAGNETIC INDUCTION
passing wire through a magnetic field
EMF induced
can make current flow if wire part of complete circuit
current can be detected by galvanometer
EMF induced proportional to the rate at which the magnetic field lines are cut
increasing induced EMF
moving the wire faster
using a stronger magnet
increasing length of wire in magnetic field
reversing current and EMF direction
moving wire in opposite direction
turning magnet around to reverse direction of magnetic field
current direction given by Fleming's right hand rule
thumb: motion
index finger: field
middle finger: induced emf
bar magnet pushed into coil
increasing induced EMF and current
moving the magnet faster
using a stronger magnet
increasing the number of turns in the coil
reversing direction of induced EMF
moving magnet in opposite direction / pulling away
reversing magnet
current induced
induced current flows opposite the change that produced it
pole of coil and magnet are same when magnet is in coil
poles are opposite when magnet away from coil
current direction given by right hand grip rule
fingers point in conventional current direction
thumb gives North Pole of magnet
