fleming's left-hand rule

Question 1

what is the motor effect?

Answer 1

when a conductor carrying a current (therefore exerting a magnetic field) is placed in a magnetic field the magnet producing the field and the conductor exert a force on each other

Question 2

what does fleming’s left hand rule show?

Answer 2

the relative orientation of the force, the current in the
conductor and the magnetic field

Question 3

what does each finger/thumb represent?

Answer 3

thumb - force
first finger - field
second finger - current

Question 4

list 4 factors affecting size of force on conductor

Answer 4

• strength of current
• strength of magnetic field
• length of wire
• angle between field lines and current

Question 5

force equation

Answer 5

F=BIL
force = magnetic flux density x current x length
N, T, A, m

Question 6

what must occur to experience the full force?

Answer 6

wire has to be perpendicular to magnetic field, if it runs parallel, no force will occur
