Four particles enter a magnetic
field. They are a neutron, an
electron, a proton, and an alpha
particle (+2). Which track is the
proton?
If an iron bar is placed in a
magnetic field, which one of the
figures represents the distortion of
the field?
What is the strength of the B-field
at point P?
What is the direction of the Bfield at point P?
Electrons flow along a wire
directed out of the page. What is
the direction of the magnetic
force on the wire?
What is the magnitude of the B-field
at point P, if the current is 1 A?
