1.     The rule for the interaction of magnetic poles is similar to the rule for electric?

• a) Resistance

• b) Current

• c) Capacitance

• Charge

1.     Regarding magnetic materials, which of the following materials is considered non-magnetic?

• a) Iron

• b) Platinum

• c) Nickel

• d) Cobalt

1.     What type of materials are strongly attracted by magnets, according to the information provided?

• a) Platinum

• b) Aluminum

• c) Iron

• d) Carbon

1.     Which materials are mentioned as being only slightly attracted by a magnet and are considered non-magnetic in the provided information?

• Iron and steel

• Nickel and cobalt

• Platinum and aliminum

• Iron and nickel

1.     What is a common characteristic of materials considered non-magnetic?

• They are strongly attracted by magnets.

• They are only slightly attracted by magnets

• They have no reactions to magnets

• They repel magnets.

1.     Magnetism is a measurable characteristic of a moving electrical charge. An electron and its spin moving about the nucleus of an atom both produce a magnetic field. If the magnetism produced by an electron moving in one direction is counteracted by the magnetism of an electron moving in the opposite direction, what is the net magnetism?

a) Zero

• Zero

•  Positive

• Negative

• Indeterminate

1.     Atoms that have an electron arrangement resulting in a value of magnetism greater than zero in one direction are said to have a:

• Negative magnetic moment

• Positve magnetic moment

• Zero magnetic moment

• Indeterminate magnetic moment

1.     According to the classification of magnets, what are the two categories of magnets based on how long they retain a magnetic effect after being magnetized?

• North and South

• Strong and Weak

• Temporary and Parmanent

• Iron and Steel

1.     What is the defining characteristic of temporary magnets?

• They are always aligned

• They are aligned only temporarily

• They have a permanent magnetic effect

• They require a strong external force

1.     What is a characteristic of permanent magnets?

• They require constant magnetizing force

• They are only temporarily magnetic

• They lose their magnetic effect over time

• They are aligned only temporarily
