A)
1) A thin metal strip sets itself at right angles to the flux lines in a
magnetic field. The metal may be classified as:
A) paramagnetic B) diamagnetic C) ferromagnetic D)
antimagnetic
2) Nickel and cobalt are both:
A) paramagnetic B) diamagnetic C) ferromagnetic D)
antimagnetic
3) Which one of the following materials is not ferromagnetic?
A) Iron B) aluminum C) nickel D) colbalt
4) The element bismuth is the outstanding example of a
substance which is
A) paramagnetic B) diamagnetic C) ferromagnetic D)
antimagnetic
5) A piece of metal is attracted to one pole of a large magnet.
Describe how you could whether the metal is ferromagnetic or a
permanent magnet.
Magnetic Domains


Describe a method by which magnetic domains
can be observed.
How are the domains arranged in an
unmagnetized ferromagnetic piece of material?
Define each of the following:
a) declination
b) Inclination (dip angle)
c) permeability
d) retentivity
Magnetic Laws
Which one of the following statements concerning
permanent magnets is false?
a) The north pole of a permanent magnet is attracted to a
south pole.
b) All permanent magnets are surrounded by a magnetic
field.
c) The direction of a magnetic field is indicated by the
north pole of a compass.
d) The direction of a magnetic field is indicated by the
north pole of a compass.
e) Where a permanent magnet is cut in half, one piece will
be a north pole and one piece will be a south pole.
