COMPLETE SOLUTIONS!!
when electrons are forced to move thru a conductor the magnetic fields of
individual electrons subtract from one another
T or F Answer - False
the direction of the electromagnetic field around a conductor because of
current flow is determined by the right hand rule as it relates to the electron
theory
T or F Answer - false
the field intensity around the conductor carrying current increased current flow
and is stronger the further the distance from the conductor
T or F Answer - false
if a conductor carrying current is next to another conductor carrying current in
the opposite direction the electromagnetic field attempts to push the
conductor apart
T or F Answer - True
,when conductors carrying current in the same direction are brought together
the electromagnetic fields attempting to pull the conductor together
T or F Answer - True
if a conductor is twisted to form a loop the electromagnetic fields around the
conductor are compressed to create a dense and strong electromagnetic field
T or F Answer - true
if conductor loops are wound in the same direction the conductors
electromagnetic fields add together
T or F Answer - True
the electromagnetic field of a coil can be made stronger by placing a soft iron
core inside of the coil windings
T or F Answer - True
the strength of an electromagnetic field depends on the magnitude of the
current and the number of turns in the electromagnetic coil
T or F Answer - True
