Magnetism

Question 1

Definition: a physical phenomenon produced by the motion of electric charge, resulting in attractive and repulsive forces between objects.
The strength of the force depends on the separation between the two magnets in question.
MAGNETIC FORCES IS INVERSELY PROPORTIONAL TO THE DISTANCE BETWEEN THE TWO MAGNETS BEING ANALYZED.

Answer 1

Magnetism

Question 2

Definition: each of the two points or region of an artificial or natural magnet to and from which the lines of magnet force are directed
The end that points northward is called
The end that points southward is called
LIKE POLES REPEL; OPPOSITE POLES ATTRACT

Answer 2

Magnetic Poles

NORTH-SEEKING POLE
SOUTH-SEEKING POLE

Question 3

Definition: the space around, in which a magnetic force is exerted
The shape of a ……. is revealed by
………. lines spreadout from one pole, curve around the magnet, and return to the other pole.
THE DIRECTION OF THE MAGNETIC FIELD OUTSIDE A MAGNET IS FROM THE NORTH POLE TO THE SOUTH POLE.

Answer 3

Magnetic Fields

MAGNETIC FIELD LINES

Question 4

A magnetic field is produced by the motion of electric charge
The motion of electric charge is surrounded by a magnetic field
A current- carrying wire loop is called an

Answer 4

ELECTROMAGNET

Question 5

Since a charged particle moving through a magnetic field experiences a deflecting force, a current of charged particles moving through a magnetic field also experiences a deflecting force.
A moving charge is deflecting when it crosses magnetic field lines but not when it travels parallel to the field lines.

Answer 5

Forces

Question 6

Materials become magneized of
Definition: clusters of aligned atoms
Permanent magnets are made by simply placing pieces of iron or certain iron alloys in strong magnetic fields.

Answer 6

MAGNETIC DOMAINS
