Magnetic Effect of Electric Current
magnetic filed lines
high density lines means high strength of field
field lines never cross
drawn from north to south
magnetic field lines due to current in conductor
strength of magnetic field in solenoid high
when the current is high
when we add an iron core in the solenoid
when number of turns of coils is high
force between magnet and conductor
force acting on a charge q at speed v and at angle theta to magnetic field strength B
equation involve
F = Bqv sin theta
field produce due to
circular field of wire
uniform field of magnet
changes occur from electrical energy to kinetic energy
