26
Q

Force exists between all charged particles. It is an attraction or repulsion between any two charged objects.

A

Electric Force

27
Q

What is the relationship between any two charged objects.

A

Attraction or repulsion between any two charged objects.

28
Q

The strength of the Electric forces depends on what?

A

The strength of an electric force depends on the size, or magnitude, of the charges and the distance between them.

29
Q

What are negative charges?

A

Electrons

30
Q

What are positive charges?

A

Protons

31
Q

What charges repel?

A

Like charges will repel. The charges will push each other away.

32
Q

What charges attract?

A

Unlike charges will attract. The charges will push each other together.

33
Q

What happens when electrons move easily from one atom to another?

A

Imbalance of electrons

34
Q

If an atom has an equal number of protons and electrons.

A

Then, the atom is electrically neutral, no electrical charge.

35
Q

If an atom has an unequal number of protons and electrons…

A

Then, the atom is electrically charged.

36
Q

It is an atom or molecule that has an electric charge.

A

Ion

37
Q

What makes an atom different from an ion?

A

An atom is electrically neutral; the same number of protons and electrons; and the number of protons identify the element.

38
Q

What makes an ion different from an atom?

A

An ion is electrically charged; a different number of protons and electrons; and may have more than one atom.

39
Q

Ions with a positive charge

A

Cations

40
Q

Ions with a negative charge

A

Anions.

41
Q

It is a plasma created from an imbalance of free electrons meeting up with the positive charges on Earth.

A

Lightning

42
Q

A force that a magnet exerts on certain materials like iron, steel, nickel, and cobalt.

A

Magnetic force

43
Q

It contains magnetic properties even after the magnetic field is removed.

A

Ferromagnetism.

44
Q

Referred to materials like aluminum and platinum which can become magnetized in a magnetic field, but their magnetism disappears once the magnetic field is removed.

A

Paramagnetism

45
Q

Why is a magnetic force a non-contact force?

A

It can act from a distance. The magnet produces a magnetic field that when it is close enough will attract to the object.

46
Q

What is the relationship between the object and the magnet?

A

The magnet and the object may attract or repel.

47
Q

A magnet has two poles.

A

There is the North Pole and the South Pole.

48
Q

Name the different shapes of a magnet.

A

Bar magnet; U shape magnet; neodymium; Electromagnet; needle magnet; and Horseshoe.

49
Q

Like poles of a magnet

A

Repel

50
Q

Unlike poles of a magnet

A

Attract

51
Q

An area around the magnet that has a magnetic force.

A

A magnetic field

52
Q

Where is the strongest strength of a magnet?

A

Closest to the poles

53
Q

This magnet has a North and South Pole; is temporary since they lose their magnetic property once not in contact with a magnet.

A

Temporary magnets

54
Q

Iron nails and paper clips are examples of this type of magnet.

A

Temporary magnets

55
Q

This magnet has a magnetic field; has a North and South Pole; and is permanent since they do not lose their magnetic property once they are magnetized.

A

Permanent magnets

56
Q

This type of magnet consists of a coil of wire wrapped around the metal core made from iron. It needs an electrical current to create a magnetic field, making the material behave like a magnet.

A

Electromagnets

57
Q

This type of magnet has a magnetic field; has a North and South Pole; and is temporary since the magnetic field can be turned off and on.

A

Electromagnets

58
Q

What are the five (5) characteristics of a magnet?

A

The characteristics of a Magnet:

Attractive Property; Directive Property; Law of Magnetic Poles;
Pair Property; and Sure test of magnetism

59
Q

This property proves that the
magnetic strength at the ends of the poles is strong.

A

Attractive Property

60
Q

This property helps to understand
which pole of the magnet is north and south by suspending
the magnet in mid-air. A freely suspended magnet always
comes to rest pointing to the Earth’s north-south direction.

A

Directive Property

61
Q

Like poles repel while unlike poles attract.

A

Law of Magnetic Poles

62
Q

When a magnet is cut in half, both
the pieces will form a new North and South pole.

A

Pair Property

63
Q

A test is made of an iron rod is
magnetized or not by checking its attraction or its repulsion
to the magnet.

A

Sure test of magnetism

64
Q

What force is used in a Roller coaster?

A

Magnetic Force
