Question	Answer
Force on current-carrying conductor in magnetic field	F = ILB
Reason for force occurring on a current-carrying conductor in a magnetic field	The conductor has a magnetic field around it, which interacts with the magnetic field it is placed in, and this creates a force
Thumb in left hand rule	Direction of force
First finger in left hand rule	Direction of magnetic field
Second finger in left hand rule	Direction of current
Force on a charged particle moving through a magnetic field	F = qvB
Forces between currents	If two current-carrying conductors are placed in close proximity to one another, they will exert a force on one another due to their magnetic fields
Ampere	the steady current which, if maintained in two straight parallel conductors of infinite length, of negligible cross section and placed one metre apart in a vacuum would produce a force on each conductor of 2 × 10*-7 newtons per metre of length
