number of turns is large
number of turns is less
plane of the coil is perpendicular to the magnetic field
area of the coil is small
the ball becomes positively charged by induction
the ball becomes negatively charged by induction
there is a rearrangement of the electrons in the ball
the number of electrons in the ball is more than the number of electrons on the rod
must be convergent

intersect inside the body of the magnet
intersect at neutral points only
intersect only at north and south poles
cannot intersect at all
A vertical plane passing through the axis of a freely suspended magnet is called the magnetic meridian
A vertical plane passing through the axis of rotation of the Earth is called the geographical meridian
The degree to whici1 the maonetic field can penetrate a medium is known as the relative permeability of the medium
The relative permeability is not a dimensionless quantity
circular
parabolic
elliptic
a straight line
The proton and the electron experience equal and opposite force
The proton experiences greater force than does the electron
The electron experiences more force than does the proton
No moving charged particle experiences a force in a magnetic field
A force
A torque
Both a force and a torque
Neither a force nor a torque
